Background ========== PCRE is a Perl-compatible regular expression library. GLib includes a copy of PCRE. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libpcre < 7.6-r1 >= 7.6-r1 2 dev-libs/glib < 2.14.6 >= 2.14.6 < 2.14.0 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== PCRE contains a buffer overflow vulnerability when processing a character class containing a very large number of characters with codepoints greater than 255. Impact ====== A remote attacker could exploit this vulnerability by sending a specially crafted regular expression to an application making use of the PCRE library, which could possibly lead to the execution of arbitrary code or a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All PCRE users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libpcre-7.6-r1" All GLib users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.14.6" References ========== [ 1 ] CVE-2008-0674 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0674 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200803-24.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.
