CentOS 5 / 6 / 7 : glibc (CESA-2014:1110)

high Nessus Plugin ID 77439

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

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.

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 traversal 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.

Solution

Update the affected glibc packages.
