Overview

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly. A flaw was found in the way BIND performed DNSSEC validation. An attacker able to make BIND (functioning as a DNS resolver with DNSSEC validation enabled) resolve a name in an attacker-controlled domain could cause named to exit unexpectedly with an assertion failure. (CVE-2015-4620) Red Hat would like to thank ISC for reporting this issue. All bind users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, the BIND daemon (named) will be restarted automatically.

Overview

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly. A denial of service flaw was found in the way BIND parsed certain malformed DNSSEC keys. A remote attacker could use this flaw to send a specially crafted DNS query (for example, a query requiring a response from a zone containing a deliberately malformed key) that would cause named functioning as a validating resolver to crash. (CVE-2015-5722) Red Hat would like to thank ISC for reporting this issue. Upstream acknowledges Hanno Böck as the original reporter.

Overview

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly. A denial of service flaw was found in the way BIND processed certain records with malformed class attributes. A remote attacker could use this flaw to send a query to request a cached record with a malformed class attribute that would cause named functioning as an authoritative or recursive server to crash. (CVE-2015-8000) Note: This issue affects authoritative servers as well as recursive servers, however authoritative servers are at limited risk if they perform authentication when making recursive queries to resolve addresses for servers listed in NS RRSETs.

Overview

dbus-glib is an add-on library to integrate the standard D-Bus library with the GLib main loop and threading model. A flaw was found in the way dbus-glib filtered the message sender (message source subject) when the "NameOwnerChanged" signal was received. This could trick a system service using dbus-glib (such as fprintd) into believing a signal was sent from a privileged process, when it was not. A local attacker could use this flaw to escalate their privileges. (CVE-2013-0292) All dbus-glib users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Overview

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. A stack-based buffer overflow was found in the way the libresolv library performed dual A/AAAA DNS queries. A remote attacker could create a specially crafted DNS response which could cause libresolv to crash or, potentially, execute code with the permissions of the user running the library. Note: this issue is only exposed when libresolv is called from the nss_dns NSS service module. (CVE-2015-7547) This issue was discovered by the Google Security Team and Red Hat. This update also fixes the following bugs: * The dynamic loader has been enhanced to allow the loading of more shared libraries that make use of static thread local storage. While static thread local storage is the fastest access mechanism it may also prevent the shared library from being loaded at all since the static storage space is a limited and shared process-global resource. Applications which would previously fail with "dlopen: cannot load any more object with static TLS" should now start up correctly. (BZ#1291270) * A bug in the POSIX realtime support would cause asynchronous I/O or certain timer API calls to fail and return errors in the presence of large thread-local storage data that exceeded PTHREAD_STACK_MIN in size (generally 16 KiB). The bug in librt has been corrected and the impacted APIs no longer return errors when large thread-local storage data is present in the application.

Overview

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. A padding oracle flaw was found in the Secure Sockets Layer version 2.0 (SSLv2) protocol. An attacker can potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack is publicly referred to as DROWN. (CVE-2016-0800) Note: This issue was addressed by disabling the SSLv2 protocol by default when using the 'SSLv23' connection methods, and removing support for weak SSLv2 cipher suites. For more information, refer to the knowledge base article linked to in the References section. A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that have been disabled on the server. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks. (CVE-2015-3197) A side-channel attack was found that makes use of cache-bank conflicts on the Intel Sandy-Bridge microarchitecture. An attacker who has the ability to control code in a thread running on the same hyper-threaded core as the victim's thread that is performing decryption, could use this flaw to recover RSA private keys. (CVE-2016-0702) A double-free flaw was found in the way OpenSSL parsed certain malformed DSA (Digital Signature Algorithm) private keys. An attacker could create specially crafted DSA private keys that, when processed by an application compiled against OpenSSL, could cause the application to crash. (CVE-2016-0705) An integer overflow flaw, leading to a NULL pointer dereference or a heap-based memory corruption, was found in the way some BIGNUM functions of OpenSSL were implemented. Applications that use these functions with large untrusted input could crash or, potentially, execute arbitrary code. (CVE-2016-0797) Red Hat would like to thank the OpenSSL project for reporting these issues.

Overview

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library. Security Fix(es): * A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. (CVE-2016-2108) * Two integer overflow flaws, leading to buffer overflows, were found in the way the EVP_EncodeUpdate() and EVP_EncryptUpdate() functions of OpenSSL parsed very large amounts of input data. A remote attacker could use these flaws to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. (CVE-2016-2105, CVE-2016-2106) * It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. A remote attacker could possibly use this flaw to retrieve plain text from encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2016-2107) * Several flaws were found in the way BIO_*printf functions were implemented in OpenSSL. Applications which passed large amounts of untrusted data through these functions could crash or potentially execute code with the permissions of the user running such an application. (CVE-2016-0799, CVE-2016-2842) * A denial of service flaw was found in the way OpenSSL parsed certain ASN.1-encoded data from BIO (OpenSSL's I/O abstraction) inputs. An application using OpenSSL that accepts untrusted ASN.1 BIO input could be forced to allocate an excessive amount of data. (CVE-2016-2109) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-2108, CVE-2016-2842, CVE-2016-2105, CVE-2016-2106, CVE-2016-2107, and CVE-2016-0799.

Overview

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library. Security Fix(es): * A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support. (CVE-2016-6304) * It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm (DSA) signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system. (CVE-2016-2178) * It was discovered that the Datagram TLS (DTLS) implementation could fail to release memory in certain cases. A malicious DTLS client could cause a DTLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory. (CVE-2016-2179) * A flaw was found in the Datagram TLS (DTLS) replay protection implementation in OpenSSL. A remote attacker could possibly use this flaw to make a DTLS server using OpenSSL to reject further packets sent from a DTLS client over an established DTLS connection. (CVE-2016-2181) * An out of bounds write flaw was discovered in the OpenSSL BN_bn2dec() function. An attacker able to make an application using OpenSSL to process a large BIGNUM could cause the application to crash or, possibly, execute arbitrary code. (CVE-2016-2182) * A flaw was found in the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite. (CVE-2016-2183) This update mitigates the CVE-2016-2183 issue by lowering priority of DES cipher suites so they are not preferred over cipher suites using AES. For compatibility reasons, DES cipher suites remain enabled by default and included in the set of cipher suites identified by the HIGH cipher string. Future updates may move them to MEDIUM or not enable them by default. * An integer underflow flaw leading to a buffer over-read was found in the way OpenSSL parsed TLS session tickets. A remote attacker could use this flaw to crash a TLS server using OpenSSL if it used SHA-512 as HMAC for session tickets. (CVE-2016-6302) * Multiple integer overflow flaws were found in the way OpenSSL performed pointer arithmetic. A remote attacker could possibly use these flaws to cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2016-2177) * An out of bounds read flaw was found in the way OpenSSL formatted Public Key Infrastructure Time-Stamp Protocol data for printing. An attacker could possibly cause an application using OpenSSL to crash if it printed time stamp data from the attacker. (CVE-2016-2180) * Multiple out of bounds read flaws were found in the way OpenSSL handled certain TLS/SSL protocol handshake messages. A remote attacker could possibly use these flaws to crash a TLS/SSL server or client using OpenSSL. (CVE-2016-6306) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-6304 and CVE-2016-6306 and OpenVPN for reporting CVE-2016-2183.

Overview

Kerberos is a networked authentication system which allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos KDC. A memory leak flaw was found in the krb5_unparse_name() function of the MIT Kerberos kadmind service. An authenticated attacker could repeatedly send specially crafted requests to the server, which could cause the server to consume large amounts of memory resources, ultimately leading to a denial of service due to memory exhaustion. (CVE-2015-8631) An out-of-bounds read flaw was found in the kadmind service of MIT Kerberos. An authenticated attacker could send a maliciously crafted message to force kadmind to read beyond the end of allocated memory, and write the memory contents to the KDC database if the attacker has write permission, leading to information disclosure.

Overview

Network Security Services (NSS) is a set of libraries designed to support cross-platform development of security-enabled client and server applications. A flaw was found in the way the TLS protocol composes the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in NSS to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Future updates may raise this limit to 1024 bits. The nss and nss-util packages have been upgraded to upstream versions 3.19.1. The upgraded versions provide a number of bug fixes and enhancements over the previous versions. Users of nss and nss-util are advised to upgrade to these updated packages, which fix these security flaws, bugs, and add these enhancements.

Overview

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. A flaw was found in the way TLS 1.2 could use the MD5 hash function for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker able to force a TLS connection to use the MD5 hash function could use this flaw to conduct collision attacks to impersonate a TLS server or an authenticated TLS client. (CVE-2015-7575) All nss users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all services linked to the NSS library must be restarted, or the system rebooted.

Overview

Network Security Services (NSS) is a set of libraries designed to support cross-platform development of security-enabled client and server applications. A flaw was found in the way the TLS protocol composes the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in NSS to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Future updates may raise this limit to 1024 bits. The nss and nss-util packages have been upgraded to upstream versions 3.19.1. The upgraded versions provide a number of bug fixes and enhancements over the previous versions. Users of nss and nss-util are advised to upgrade to these updated packages, which fix these security flaws, bugs, and add these enhancements.

Overview

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. The nss-util packages provide utilities for use with the Network Security Services (NSS) libraries. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities. The following packages have been upgraded to a newer upstream version: nss 3.21.0, nss-util 3.21.0, nspr 4.11.0. (BZ#1300629, BZ#1299874, BZ#1299861) Security Fix(es): * A use-after-free flaw was found in the way NSS handled DHE (Diffie-Hellman key exchange) and ECDHE (Elliptic Curve Diffie-Hellman key exchange) handshake messages. A remote attacker could send a specially crafted handshake message that, when parsed by an application linked against NSS, would cause that application to crash or, under certain special conditions, execute arbitrary code using the permissions of the user running the application. (CVE-2016-1978) * A use-after-free flaw was found in the way NSS processed certain DER (Distinguished Encoding Rules) encoded cryptographic keys. An attacker could use this flaw to create a specially crafted DER encoded certificate which, when parsed by an application compiled against the NSS library, could cause that application to crash, or execute arbitrary code using the permissions of the user running the application. (CVE-2016-1979) Red Hat would like to thank the Mozilla Project for reporting these issues. Upstream acknowledges Eric Rescorla as the original reporter of CVE-2016-1978; and Tim Taubert as the original reporter of CVE-2016-1979.
