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
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to

Red Hat: 2012:1265-01: libxslt: Important Advisory

Updated libxslt packages that fix several security issues are now available for Red Hat Enterprise Linux 5 and 6

Summary

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)
