Debian Security Advisory DSA-2277-1 security@debian.org
http://www.debian.org/security/ Nico Golde
July 10, 2011 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : xml-security-c
Vulnerability : stack-based buffer overflow
Problem type : local/remote
Debian-specific: no
CVE ID : CVE-2011-2516
Debian bug : 632973
It has been discovered that xml-security-c, an implementation of the XML
Digital Signature and Encryption specifications, is not properly handling
RSA keys of sizes on the order of 8192 or more bits. This allows an
attacker to crash applications using this functionality or potentially
execute arbitrary code by tricking an application into verifying a signature
created with a sufficiently long RSA key.
For the oldstable distribution (lenny), this problem has been fixed in
version 1.4.0-3+lenny3.
For the stable distribution (squeeze), this problem has been fixed in
version 1.5.1-3+squeeze1.
For the testing distribution (wheezy), this problem will be fixed soon.
For the unstable distribution (sid), this problem has been fixed in
version 1.6.1-1.
We recommend that you upgrade your xml-security-c packages.
