Summary
Red Hat Security Advisory: pcre security update
Notes
Topic
Updated pcre packages that resolve several security issues are now
available for Red Hat Enterprise Linux 4.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
Details
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, such as Konqueror,
parses a malicious regular expression, it may have been possible to run
arbitrary code as the user running the application.
(CVE-2006-7225, CVE-2006-7226, CVE-2006-7228, CVE-2006-7230, CVE-2007-1659)
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.
