Synopsis

========

 

A vulnerability was found in libxslt, possibly resulting in the

execution of arbitrary code and Denial of Service.

 

Background

Libxslt is the XSLT C library developed for the GNOME project. XSLT

itself is an XML language to define transformations for XML.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 dev-libs/libxslt < 1.1.24 >= 1.1.24

 

Description

===========

 

Anthony de Almeida Lopes reported a vulnerability in libxslt when

handling XSL style-sheet files, which could be exploited to trigger the

use of uninitialized memory, e.g. in a call to "free()".

 

Impact

======

 

A remote attacker could entice a user or automated system to process an

XML file using a specially crafted XSL transformation file, possibly

resulting in the execution of arbitrary code or a Denial of Service.

 

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-1.1.24"
