    James Forshaw from Context Information Security discovered several
    vulnerabilities in xml-security-c, an implementation of the XML Digital
    Security specification. The Common Vulnerabilities and Exposures project
    identifies the following problems:
    
    CVE-2013-2153
    
        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-2013-2154
    
        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-2013-2155
    
        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-2013-2156
    
        A heap overflow exists in the processing of the PrefixList attribute
        optionally used in conjunction with Exclusive Canonicalization,
        potentially allowing arbitary code execution.
    
    For the oldstable distribution (squeeze), these problems have been fixed in
    version 1.5.1-3+squeeze2.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 1.6.1-5+deb7u1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1.6.1-6.
    
    We recommend that you upgrade your xml-security-c packages.
