Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Compress::Raw::Zlib and Compress::Raw::Bzip2 are Perl low-level interfaces to the zlib and bzip2 compression libraries. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 perl-core/Compress-Raw-Zlib < 2.020 >=3D 2.020 2 perl-core/Compress-Raw-Bzip2 < 2.020 >=3D 2.020 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Leo Bergolth reported an off-by-one error in the inflate() function in Zlib.xs of Compress::Raw::Zlib, possibly leading to a heap-based buffer overflow (CVE-2009-1391). Paul Marquess discovered a similar vulnerability in the bzinflate() function in Bzip2.xs of Compress::Raw::Bzip2 (CVE-2009-1884). Impact =3D=3D=3D=3D=3D=3D A remote attacker might entice a user or automated system (for instance running SpamAssassin or AMaViS) to process specially crafted files, possibly resulting in a Denial of Service condition. Workaround =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D There is no known workaround at this time. Resolution =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D All Compress::Raw::Zlib users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose =3Dperl-core/Compress-Raw-Zlib-2.020 All Compress::Raw::Bzip2 users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose =3Dperl-core/Compress-Raw-Bzip2-2.020 References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [ 1 ] CVE-2009-1391 http://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2009-1391 [ 2 ] CVE-2009-1884 http://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2009-1884 Availability =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200908-07.xml Concerns? =3D=3D=3D=3D=3D=3D=3D=3D=3D Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
