Synopsis
========
A vulnerability in libxslt could result in Denial of Service.

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 < 1.1.26-r3 >= 1.1.26-r3

Description
===========
An out of bounds read error has been found in libxslt/pattern.c in
libxslt.

Impact
======
A remote attacker could entice a user to process an XML file using a
specially crafted XSLT stylesheet 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-1.1.26-r3"

References
