(RHSA-2013:0668) Moderate: boost security update

The boost packages provide free, peer-reviewed, portable C++ source
libraries with emphasis on libraries which work well with the C++ Standard
Library.

A flaw was found in the way the ordered_malloc() routine in Boost sanitized
the ‘next_size’ and ‘max_size’ parameters when allocating memory. If an
application used the Boost C++ libraries for memory allocation, and
performed memory allocation based on user-supplied input, an attacker could
use this flaw to crash the application or, potentially, execute arbitrary
code with the privileges of the user running the application.
(CVE-2012-2677)

All users of boost are advised to upgrade to these updated packages, which
contain a backported patch to fix this issue.
