Synopsis
========
Multiple Denial of Service vulnerabilities have been found in libxslt.
Background
==========
libxslt is the XSLT C library developed for the GNOME project. XSLT is
an XML language to define transformations for XML.
Affected packages
=================
——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 dev-libs/libxslt < 1.1.28 >= 1.1.28
Description
===========
Multiple vulnerabilities have been found in libxslt:
* Multiple errors exist in pattern.c and functions.c (CVE-2012-2870,
CVE-2012-6139).
* A double-free error exists in templates.c (CVE-2012-2893).
* A NULL pointer dereference in keys.c (CVE-2012-6139).
* An error in handling stylesheets containing DTDs (CVE-2013-4520).
Impact
======
A remote attacker could entice a user to process a specially crafted
file in an application linked against libxslt, possibly resulting in a
Denial of Service condition.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All libxslt users should upgrade to the latest version:
# emerge –sync
# emerge –ask –oneshot –verbose “>=dev-libs/libxslt-1.1.28”
Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these
packages.
