 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.
