high Nessus Plugin ID 66917

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the xml-security-c packages.

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.
