"This update re-based pcre to version 7.3 as used in Fedora 8 to
address multiple security issues that cause memory corruption, leading
to application crash or possible execution of arbitrary code.
CVE-2007-1659 (#315871), CVE-2007-1661 (#392931), CVE-2007-1662
(#392921), CVE-2007-4766 (#392891), CVE-2007-4767 (#392901),
CVE-2007-4768 (#392911), CVE-2008-0674 (#431660) This issue may affect
usages of pcre, where regular expressions from untrusted sources are
compiled. Handling of untrusted data using trusted regular expressions
is not affected by these problems.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
