Gentoo Linux Security Advisory

Title: libxml2: User-assisted execution of arbitrary code (GLSA 201207-02)
Severity: normal
Exploitable: remote
Date: July 09, 2012
Bug(s): #416209
ID: 201207-02

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

Package: dev-libs/libxml2
Vulnerable: < 2.8.0_rc1
Unaffected: >= 2.8.0_rc1
Architectures: All supported architectures


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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.8.0_rc1"
