Security Advisory: Low
Updated boost packages that fix two security issues and two bugs are now
available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having low
security impact. Common Vulnerability Scoring System (CVSS) base scores,

The boost packages provide free, peer-reviewed, portable C++ source
libraries with emphasis on libraries which work well with the C++ Standard
Library.
Invalid pointer dereference flaws were found in the way the Boost regular
expression library processed certain, invalid expressions. An attacker able
to make an application using the Boost library process a specially-crafted
regular expression could cause that application to crash or, potentially,
execute arbitrary code with the privileges of the user running the
application. (CVE-2008-0171)
NULL pointer dereference flaws were found in the way the Boost regular
