3. Problem description:
PCRE is a Perl-compatible regular expression library.
Flaws were discovered in the way PCRE handles certain malformed regular
expressions. If an application linked against PCRE parses a malicious
regular expression, it may have been possible to run arbitrary code as the
user running the application. (CVE-2006-7228, CVE-2007-1660)
Users of PCRE are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
Red Hat would like to thank Ludwig Nussel for reporting these issues.
