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

Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


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.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 7.8
(CVSS2#E:POC/RL:OF/RC:C)
