libxml2: Denial of Service

libxml2: Denial of Service A hash collision vulnerability in libxml2 allows remote attackers to cause a Denial of Service condition. libxml2 March 06, 2012 March 06, 2012: 1 405261 remote 2.7.8-r5 2.7.8-r5

libxml2 is the XML C parser and toolkit developed for the Gnome project.

libxml2 does not properly randomize hash functions to protect against hash collision attacks.

A remote attacker could entice a user or automated system to open a specially crafted XML document with an application using libxml2 resulting in a Denial of Service condition.

There is no known workaround at this time.

All libxml2 users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.7.8-r5"
