Gentoo Linux Security Advisory

Title: libxslt: Execution of arbitrary code (GLSA 200806-02)
Severity: normal
Exploitable: remote
Date: June 03, 2008
Bug(s): #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: dev-libs/libxslt
Vulnerable: < 1.1.24
Unaffected: >= 1.1.24
Architectures: All supported architectures


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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.24"
