Severity: Normal
Title: libxslt: Execution of arbitrary code
Date: June 03, 2008
Bugs: #222499
ID: 200806-02


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 &quot;&gt;=dev-libs/libxslt-1.1.24&quot;
