RHEL 5 : glibc (RHSA-2012:0397)
critical Nessus Plugin ID 58394

Synopsis
The remote Red Hat host is missing a security update for glibc.Description
The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:0397 advisory.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. (CVE-2012-0864)
All users of glibc are advised to upgrade to these updated packages, which contain a patch to resolve this issue.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL glibc package based on the guidance in RHSA-2012:0397.See Also
