Debian DSA-2277-1 : xml-security-c - stack-based buffer overflow

medium Nessus Plugin ID 55555

Language:

Synopsis

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

Description

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.

Solution

Upgrade the xml-security-c packages.

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.
