3. Description:

 

libxslt is a library for transforming XML files into other textual formats

(including HTML, plain text, and other XML representations of the

underlying data) using the standard XSLT stylesheet transformation

mechanism.

 

A heap-based buffer overflow flaw was found in the way libxslt applied

templates to nodes selected by certain namespaces. An attacker could use

this flaw to create a malicious XSL file that, when used by an application

linked against libxslt to perform an XSL transformation, could cause the

application to crash or, possibly, execute arbitrary code with the

privileges of the user running the application. (CVE-2012-2871)

 

Several denial of service flaws were found in libxslt. An attacker could

use these flaws to create a malicious XSL file that, when used by an

application linked against libxslt to perform an XSL transformation, could

cause the application to crash. (CVE-2012-2825, CVE-2012-2870,

CVE-2011-3970)

 

An information leak could occur if an application using libxslt processed

an untrusted XPath expression, or used a malicious XSL file to perform an

XSL transformation. If combined with other flaws, this leak could possibly

help an attacker bypass intended memory corruption protections.

(CVE-2011-1202)

 

All libxslt users are advised to upgrade to these updated packages, which

contain backported patches to resolve these issues. All running

applications linked against libxslt must be restarted for this update to

take effect.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata
