Background ========== libpcre is a library providing functions for Perl-compatible regular expressions. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libpcre < 6.3 >= 6.3 Description =========== libpcre fails to check certain quantifier values in regular expressions for sane values. Impact ====== An attacker could possibly exploit this vulnerability to execute arbitrary code by sending specially crafted regular expressions to applications making use of the libpcre library. Workaround ========== There is no known workaround at this time. Resolution ========== All libpcre users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libpcre-6.3" References ========== [ 1 ] CAN-2005-2491 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2491 [ 2 ] SecurityTracker Alert ID 1014744 http://www.securitytracker.com/alerts/2005/Aug/1014744.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200508-17.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
