ALAS-2019-1298

  • Vulnerable module: libnghttp2
  • Introduced through: libnghttp2@1.21.1-1.4.amzn1
  • Fixed in: 1.31.1-2.5.amzn1

Detailed paths

  • Introduced through: amazonlinux:2018.03.0.20190514@* libnghttp2@1.21.1-1.4.amzn1

Overview

Package updates are available for Amazon Linux AMI that fix the following vulnerabilities: CVE-2019-9513: Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU. 1735741: CVE-2019-9513 HTTP/2: flood using PRIORITY frames results in excessive resource consumption CVE-2019-9511: Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. 1741860: CVE-2019-9511 HTTP/2: large amount of data requests leads to denial of service

ALAS-2020-1404

  • Vulnerable module: libnghttp2
  • Introduced through: libnghttp2@1.21.1-1.4.amzn1
  • Fixed in: 1.33.0-1.1.6.amzn1

Detailed paths

  • Introduced through: amazonlinux:2018.03.0.20190514@* libnghttp2@1.21.1-1.4.amzn1

Overview

Affected versions of this package are vulnerable to ALAS-2020-1404. Package updates are available for Amazon Linux AMI that fix the following vulnerabilities: CVE-2020-11080: In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection. 1844929: CVE-2020-11080 nghttp2: overly large SETTINGS frames can lead to DoS

Remediation

Upgrade libnghttp2 to version or higher.

Affected versions of this package are vulnerable to ALAS-2020-1415. Package updates are available for Amazon Linux AMI that fix the following vulnerabilities: CVE-2018-14567: libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035 and CVE-2018-9251. 1619875: CVE-2018-14567 libxml2: Infinite loop caused by incorrect error detection during LZMA decompression CVE-2018-14404: 1595985: CVE-2018-14404 libxml2: NULL pointer dereference in xmlXPathCompOpEval() function in xpath.c A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case. Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application. CVE-2017-18258: The xz_head function in xzlib.c in libxml2 before 2.9.6 allows remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality does not restrict memory usage to what is required for a legitimate file. 1566749: CVE-2017-18258 libxml2: Unrestricted memory usage in xz_head() function in xzlib.c CVE-2017-15412: Use after free in libxml2 before 2.9.5, as used in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. 1523128: CVE-2017-15412 libxml2: Use after free in xmlXPathCompOpEvalPositionalPredicate() function in xpath.c CVE-2016-5131: Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function. 1358641: CVE-2016-5131 libxml2: Use after free triggered by XPointer paths beginning with range-to CVE-2015-8035: 1277146: CVE-2015-8035 libxml2: DoS caused by incorrect error detection during XZ decompression The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.

A remote attacker could trigger this flaw via SRTP encrypt or decrypt operations, to execute arbitrary code with the permissions of the user running the application (compiled with nss). While the attack complexity is high, the impact to confidentiality, integrity, and availability are high as well. 1774831: CVE-2019-11745 nss: Out-of-bounds write when passing an output buffer smaller than the block size to NSC_EncryptUpdate When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur. This could have caused heap corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. CVE-2019-11729: 99999: CVE-2019-11729 nss: Empty or malformed p256-ECDH public keys may trigger a segmentation fault Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly sanitized before being copied into memory and used.

Overview

Package updates are available for Amazon Linux AMI that fix the following vulnerabilities: CVE-2019-1563: 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). 1752100: CVE-2019-1563 openssl: information disclosure in PKCS7_dataDecode and CMS_decrypt_set1_pkey
