Background ========== The Compress::Zlib is a Perl module which provides an interface to the zlib compression library. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-perl/Compress-Zlib < 1.35 >= 1.35 Description =========== Compress::Zlib 1.34 contains a local vulnerable version of zlib, which may lead to a buffer overflow. Impact ====== By creating a specially crafted compressed data stream, attackers can overwrite data structures for applications that use Compress::Zlib, resulting in a Denial of Service and potentially arbitrary code execution. Workaround ========== There is no known workaround at this time. Resolution ========== All Compress::Zlib users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-perl/Compress-Zlib-1.35" References ========== [ 1 ] GLSA 200507-19 http://www.gentoo.org/security/en/glsa/glsa-200507-19.xml [ 2 ] GLSA 200507-05 http://www.gentoo.org/security/en/glsa/glsa-200507-05.xml [ 3 ] CAN-2005-1849 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1849 [ 4 ] CAN-2005-2096 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2096 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200508-01.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.
