Ubuntu Security Notice USN-729-1 - Mike Wiacek discovered that the ARC2 implementation in Python Crypto did not correctly check the key length. If a user or automated system were tricked into processing a malicious ARC2 stream, a remote attacker could execute arbitrary code or crash the application using Python Crypto, leading to a denial of service.
