Updated xml-security-c package fixes multiple security vulnerabilities

Publication date: 01 Jul 2013
Type: security
Affected Mageia releases : 2 , 3
CVE: CVE-2013-2153 , CVE-2013-2154 , CVE-2013-2155 , CVE-2013-2156 , CVE-2013-2210

Description

The implementation of XML digital signatures in the Santuario-C++ library
is vulnerable to a spoofing issue allowing an attacker to reuse existing
signatures with arbitrary content (CVE-2013-2153).

A stack overflow, possibly leading to arbitrary code execution, exists in
the processing of malformed XPointer expressions in the XML Signature
Reference processing code (CVE-2013-2154).

A bug in the processing of the output length of an HMAC-based XML
Signature would cause a denial of service when processing specially chosen
input (CVE-2013-2155).

A heap overflow exists in the processing of the PrefixList attribute
optionally used in conjunction with Exclusive Canonicalization, potentially
allowing arbitrary code execution (CVE-2013-2156).

The attempted fix to address CVE-2013-2154 introduced the possibility of a
heap overflow, possibly leading to arbitrary code execution, in the
processing of malformed XPointer expressions in the XML Signature Reference
processing code (CVE-2013-2210).
