Synopsis
The remote CentOS host is missing one or more security updates.Description
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.
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 perform sufficient safety checks when loading dynamic shared objects (DSOs) to provide callbacks for its auditing API during the execution of privileged programs. A local attacker could use this flaw to escalate their privileges via a carefully-chosen system DSO library containing unsafe constructors. (CVE-2010-3856)
Red Hat would like to thank Ben Hawkes and Tavis Ormandy for reporting this issue.
All users should upgrade to these updated packages, which contain a backported patch to correct this issue.
