Background ========== Perl is a stable, cross platform programming language. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/perl < 5.8.8-r5 >= 5.8.8-r5 2 sys-devel/libperl < 5.8.8-r2 >= 5.8.8-r2 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Tavis Ormandy and Will Drewry of the Google Security Team have reported a double free vulnerability when processing a crafted regular expression containing UTF-8 characters. Impact ====== A remote attacker could possibly exploit this vulnerability to execute arbitrary code or cause a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All Perl users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/perl-5.8.8-r5" All libperl users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-devel/libperl-5.8.8-r2" References ========== [ 1 ] CVE-2008-1927 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1927 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200805-17.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.
