Uncontrolled Recursion

  • Vulnerable module: krb5/krb5-libs
  • Introduced through: krb5/krb5-libs@1.17-r0
  • Fixed in: 1.17.2-r0

Detailed paths

  • Introduced through: docker:19.03.1-dind-rootless@* krb5/krb5-libs@1.17-r0

Overview

Affected versions of this package are vulnerable to Uncontrolled Recursion. MIT Kerberos 5 (aka krb5) before 1.17.2 and 1.18.x before 1.18.3 allows unbounded recursion via an ASN.1-encoded Kerberos message because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite lengths lacks a recursion limit.

Remediation

Upgrade krb5 to version or higher.

NULL Pointer Dereference

  • Vulnerable module: openssl/libcrypto1.1
  • Introduced through: openssl/libcrypto1.1@1.1.1c-r0, openssl/libssl1.1@1.1.1c-r0 and others
  • Fixed in: 1.1.1g-r0

Detailed paths

  • Introduced through: docker:19.03.1-dind-rootless@* openssl/libcrypto1.1@1.1.1c-r0
  • Introduced through: docker:19.03.1-dind-rootless@* openssl/libssl1.1@1.1.1c-r0
  • Introduced through: docker:19.03.1-dind-rootless@* openssl/openssl@1.1.1c-r0

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference. Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f).

Remediation

Upgrade openssl to version or higher.

Use After Free

  • Vulnerable module: iproute2/iproute2
  • Introduced through: iproute2/iproute2@4.20.0-r1
  • Fixed in: 4.20.0-r2

Detailed paths

  • Introduced through: docker:19.03.1-dind-rootless@* iproute2/iproute2@4.20.0-r1

Overview

Affected versions of this package are vulnerable to Use After Free iproute2 before 5.1.0 has a use-after-free in get_netnsid_from_name in ip/ipnetns.c. NOTE: security relevance may be limited to certain uses of setuid that, although not a default, are sometimes a configuration option offered to end users. Even when setuid is used, other factors (such as C library configuration) may block exploitability.

Remediation

Upgrade iproute2 to version or higher.

Information Exposure

  • Vulnerable module: openssl/libcrypto1.1
  • Introduced through: openssl/libcrypto1.1@1.1.1c-r0, openssl/libssl1.1@1.1.1c-r0 and others
  • Fixed in: 1.1.1d-r2

  • Introduced through: docker:19.03.1-dind-rootless@* openssl/openssl@1.1.1c-r0

Overview

Affected versions of this package are vulnerable to Information Exposure. There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME. Fixed in OpenSSL 1.1.1e (Affected 1.1.1-1.1.1d). Fixed in OpenSSL 1.0.2u (Affected 1.0.2-1.0.2t).

Remediation

Upgrade openssl to version or higher.

Missing Encryption of Sensitive Data

  • Vulnerable module: openssl/libcrypto1.1
  • Introduced through: openssl/libcrypto1.1@1.1.1c-r0, openssl/libssl1.1@1.1.1c-r0 and others
  • Fixed in: 1.1.1d-r0

Detailed paths

  • Introduced through: docker:19.03.1-dind-rootless@* openssl/libcrypto1.1@1.1.1c-r0
  • Introduced through: docker:19.03.1-dind-rootless@* openssl/libssl1.1@1.1.1c-r0
  • Introduced through: docker:19.03.1-dind-rootless@* openssl/openssl@1.1.1c-r0

Overview

Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters (instead of using a named curve). In those cases it is possible that such a group does not have the cofactor present. This can occur even where all the parameters match a known named curve. If such a curve is used then OpenSSL falls back to non-side channel resistant code paths which may result in full key recovery during an ECDSA signature operation. In order to be vulnerable an attacker would have to have the ability to time the creation of a large number of signatures where explicit parameters with no co-factor present are in use by an application using libcrypto. For the avoidance of doubt libssl is not vulnerable because explicit parameters are never used. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).

NULL Pointer Dereference

  • Vulnerable module: openssl/libcrypto1.1
  • Introduced through: openssl/libcrypto1.1@1.1.1c-r0, openssl/libssl1.1@1.1.1c-r0 and others
  • Fixed in: 1.1.1i-r0

Detailed paths

  • Introduced through: docker:19.03.1-dind-rootless@* openssl/libcrypto1.1@1.1.1c-r0
  • Introduced through: docker:19.03.1-dind-rootless@* openssl/libssl1.1@1.1.1c-r0
  • Introduced through: docker:19.03.1-dind-rootless@* openssl/openssl@1.1.1c-r0

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference. The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified. OpenSSL's s_server, s_client and verify tools have support for the "-crl_download" option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue. Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w).

Remediation

Upgrade openssl to version or higher.

Use of Insufficiently Random Values

  • Vulnerable module: openssl/libcrypto1.1
  • Introduced through: openssl/libcrypto1.1@1.1.1c-r0, openssl/libssl1.1@1.1.1c-r0 and others
  • Fixed in: 1.1.1d-r0

Detailed paths

  • Introduced through: docker:19.03.1-dind-rootless@* openssl/libssl1.1@1.1.1c-r0
  • Introduced through: docker:19.03.1-dind-rootless@* openssl/openssl@1.1.1c-r0

Overview

OpenSSL 1.1.1 introduced a rewritten random number generator (RNG). This was intended to include protection in the event of a fork() system call in order to ensure that the parent and child processes did not share the same RNG state. However this protection was not being used in the default case. A partial mitigation for this issue is that the output from a high precision timer is mixed into the RNG state so the likelihood of a parent and child process sharing state is significantly reduced. If an application already calls OPENSSL_init_crypto() explicitly using OPENSSL_INIT_ATFORK then this problem does not occur at all. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c).

Overview

In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the public RSA key, using a Bleichenbacher padding oracle attack. Applications are not affected if they use a certificate together with the private RSA key to the CMS_decrypt or PKCS7_decrypt functions to select the correct recipient info to decrypt. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).
