|Summary:||The remote host is missing an update for the 'glibc'; package(s) announced via the referenced advisory.|
The remote host is missing an update for the 'glibc'
package(s) announced via the referenced 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)
This update also fixes the following bugs:
* Previously, the dynamic loader generated an incorrect ordering for
initialization according to the ELF specification. This could result in
incorrect ordering of DSO constructors and destructors. With this update,
dependency resolution has been fixed. (BZ#783999)
* Previously, locking of the main malloc arena was incorrect in the retry
path. This could result in a deadlock if an sbrk request failed. With this
update, locking of the main arena in the retry path has been fixed. This
issue was exposed by a bug fix provided in the RHSA-2012:0058 update.
* Calling memcpy with overlapping arguments on certain processors would
generate unexpected results. While such code is a clear violation of
ANSI/ISO standards, this update restores prior memcpy behavior. (BZ#799259)
All users of glibc are advised to upgrade to these updated packages, which
contain patches to resolve these issues.
glibc on Red Hat Enterprise Linux Desktop (v. 6),
