Oracle Linux 5 : glibc (ELSA-2010-0787)

Medium Nessus Plugin ID 68123


The remote Oracle Linux host is missing one or more security updates.


From Red Hat Security Advisory 2010:0787 :

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 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.


Update the affected glibc packages.
