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.
