Synopsis ========
A off-by-one error in libxml2 could result in execution of arbitrary code or Denial of Service.
Background ==========
libxml2 is the XML C parser and toolkit developed for the Gnome project.
Affected packages =================

Description ===========
The "xmlXPtrEvalXPtrPart()" function in xpointer.c contains an off-by-one error.
Impact ======
A remote attacker could entice a user or automated system to open a specially crafted XML document with an application using libxml2, possibly resulting in execution of arbitrary code or a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All libxml2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.8.0_rc1"
