Mandriva Linux Security Advisory MDVSA-2013:047
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : libxslt
Date : April 5, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

A vulnerability has been discovered and corrected in libxslt:

The XSL implementation in libxslt allows remote attackers to cause a
denial of service (incorrect read operation) via unspecified vectors
(CVE-2012-2825).

libxslt 1.1.26 and earlier does not properly manage memory, which might
allow remote attackers to cause a denial of service (application crash)
via a crafted XSLT expression that is not properly identified during
XPath navigation, related to (1) the xsltCompileLocationPathPattern
function in libxslt/pattern.c and (2) the xsltGenerateIdFunction
function in libxslt/functions.c (CVE-2012-2870).

libxml2 2.9.0-rc1 and earlier does not properly support a cast of
an unspecified variable during handling of XSL transforms, which
allows remote attackers to cause a denial of service or possibly have
unknown other impact via a crafted document, related to the _xmlNs
data structure in include/libxml/tree.h (CVE-2012-2871).

Double free vulnerability in libxslt allows remote attackers to cause
a denial of service or possibly have unspecified other impact via
vectors related to XSL transforms (CVE-2012-2893).

The updated packages have been patched to correct these issues.
