Gentoo Linux Security Advisory
Title: libxml2: Denial of Service (GLSA 201203-04)
Severity: normal
Exploitable: remote
Date: March 06, 2012
Bug(s): #405261
ID: 201203-04
Synopsis
A hash collision vulnerability in libxml2 allows remote attackers
to cause a Denial of Service condition.
Background
libxml2 is the XML C parser and toolkit developed for the Gnome project.
Affected Packages
Package: dev-libs/libxml2
Vulnerable: < 2.7.8-r5
Unaffected: >= 2.7.8-r5
Architectures: All supported architectures
Description
libxml2 does not properly randomize hash functions to protect against
hash collision attacks.
Impact
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.
Workaround
There is no known workaround at this time.
Resolution
All libxml2 users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.7.8-r5"
|
