(RHSA-2014:1110) Important: glibc security update

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.
