Detail
Problem Description: Updated glibc packages that fix two security issues are now available for Red Hat Enterprise Linux 5, 6, and 7. Red Hat Product Security has rated this update as having Important 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 (v. 5 server) - i386, ia64, ppc, s390x, x86_64 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 Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: The glibc packages contain the standard C libraries used by multiple programs on the system. These packages contain the standard C and the standard math libraries. Without these two libraries, a Linux system cannot function properly. An off-by-one heap-based buffer overflow flaw was found in glibc's internal __gconv_translit_find() function. An attacker able to make an application call the iconv_open() function with a specially crafted argument could possibly use this flaw to execute arbitrary code with the privileges of that application. (CVE-2014-5119) A directory traveral flaw was found in the way glibc loaded locale files. An attacker able to make an application use a specially crafted locale name value (for example, specified in an LC_* environment variable) could possibly use this flaw to execute arbitrary code with the privileges of that application. (CVE-2014-0475) Red Hat would like to thank Stephane Chazelas for reporting CVE-2014-0475. All glibc users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1102353 - CVE-2014-0475 glibc: directory traversal in LC_* locale handling 1119128 - CVE-2014-5119 glibc: off-by-one error leading to a heap-based buffer overflow flaw in __gconv_translit_find() |
