Detail

Buffer overflow in the PyCrypto ARC2 module 2.0.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large ARC2 key length.

Title:	DSA-1726-1 python-crypto -- buffer overflow
Description:	Mike Wiacek discovered that a buffer overflow in the ARC2 implementation of Python Crypto, a collection of cryptographic algorithms and protocols for Python allows denial of service and potentially the execution of arbitrary code. For the stable distribution, this problem has been fixed in version 2.0.1+dfsg1-2.3+lenny0. Due to a technical limitation in the Debian archive management scripts the update for the old stable distribution cannot be released synchronously. It will be fixed in version 2.0.1+dfsg1-1.2+etch0 soon. For the unstable distribution, this problem will be fixed soon. We recommend that you upgrade your python-crypto package.

Title:	USN-729-1 -- python-crypto vulnerability
Description:	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.
