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

Affected Packages:
xml-security-c
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
