RHEL 5 : glibc (RHSA-2012:0397)
Medium Nessus Plugin ID 58394
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated 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 moderate 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 provide the standard C and standard math libraries used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.
An integer overflow flaw was found in the implementation of the printf functions family. This could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort.
All users of glibc are advised to upgrade to these updated packages, which contain a patch to resolve this issue.
SolutionUpdate the affected packages.
