-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2417-1 secur...@debian.org http://www.debian.org/security/ Nico Golde February 22, 2012 http://www.debian.org/security/faq - -------------------------------------------------------------------------
Package : libxml2 Vulnerability : computational denial of service Problem type : local/remote Debian-specific: no Debug bug : 660846 CVE ID : CVE-2012-0841 It was discovered that the internal hashing routine of libxml2, a library providing an extensive API to handle XML data, is vulnerable to predictable hash collisions. Given an attacker with knowledge of the hashing algorithm, it is possible to craft input that creates a large amount of collisions. As a result it is possible to perform denial of service attacks against applications using libxml2 functionality because of the computational overhead. For the stable distribution (squeeze), this problem has been fixed in version 2.7.8.dfsg-2+squeeze3. For the testing (wheezy) and unstable (sid) distributions, this problem will be fixed soon. We recommend that you upgrade your libxml2 packages.
