Gentoo Linux Security Advisory

Title: libxslt: Denial of Service (GLSA 201203-08)
Severity: normal
Exploitable: remote
Date: March 06, 2012
Bug(s): #402861
ID: 201203-08

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: dev-libs/libxslt
Vulnerable: < 1.1.26-r3
Unaffected: >= 1.1.26-r3
Architectures: All supported architectures


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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.26-r3"
