Debian Security Advisory DSA-2710-1 Salvatore Bonaccorso
June 18, 2013
- -------------------------------------------------------------------------

Package : xml-security-c
Vulnerability : several
Problem type : local (remote)
Debian-specific: no
CVE ID : CVE-2013-2153 CVE-2013-2154 CVE-2013-2155 CVE-2013-2156

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:


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.


A stack overflow, possibly leading to arbitrary code execution,
exists in the processing of malformed XPointer expressions in the
XML Signature Reference processing code.


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.


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.
