A hash collision vulnerability in libxml2 allows remote attackers to cause a Denial of Service condition.
|Package||dev-libs/libxml2 on all architectures|
|Affected versions||< 2.7.8-r5|
|Unaffected versions||>= 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"
