"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
    arbitrary code execution."
