ALAS-2020-1404

  • Vulnerable module: libnghttp2
  • Introduced through: libnghttp2@1.31.1-2.5.amzn1
  • Fixed in: 1.33.0-1.1.6.amzn1

Detailed paths

  • Introduced through: amazonlinux:2018.03.0.20200318.1@* libnghttp2@1.31.1-2.5.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.

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.

An attacker may abuse this flaw by using a server with a hostname that has another valid hostname as a suffix (e.g., pythonicexample.com to steal cookies for example.com). When a program uses http.cookiejar.DefaultPolicy and tries to do an HTTP connection to an attacker-controlled server, existing cookies can be leaked to the attacker. This affects 2.x through 2.7.16, 3.x before 3.4.10, 3.5.x before 3.5.7, 3.6.x before 3.6.9, and 3.7.x before 3.7.3. 1740347: CVE-2018-20852 python: Cookie domain check returns incorrect results
