Detail
Problem Description: Updated libxml2 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: The libxml2 library is a development toolbox providing the implementation of various XML standards. Several denial of service flaws were found in libxml2, a library providing support for reading, modifying, and writing XML and HTML files. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or in certain cases crash the application. (CVE-2015-1819, CVE-2015-5312, CVE-2015-7497, CVE-2015-7498, CVE-2015-7499, CVE-2015-7500 CVE-2015-7941, CVE-2015-7942, CVE-2015-8241, CVE-2015-8242, CVE-2015-8317, BZ#1213957, BZ#1281955) Red Hat would like to thank the GNOME project for reporting CVE-2015-7497, CVE-2015-7498, CVE-2015-7499, CVE-2015-7500, CVE-2015-8241, CVE-2015-8242, and CVE-2015-8317.
