概要

Important: glibc security update

タイプ/重大度

Security Advisory: Important

トピック

Updated glibc packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

説明

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.

It was discovered that the glibc dynamic linker/loader did not handle the
$ORIGIN dynamic string token set in the LD_AUDIT environment variable
securely. A local attacker with write access to a file system containing
setuid or setgid binaries could use this flaw to escalate their privileges.
(CVE-2010-3847)

Red Hat would like to thank Tavis Ormandy for reporting this issue.

All users should upgrade to these updated packages, which contain a
backported patch to correct this issue.
