Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : python-crypto vulnerability (USN-729-1)

critical Nessus Plugin ID 37504

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-crypto, python-crypto-dbg and / or python2.4-crypto packages.
