Ubuntu Security Notice USN-729-1             March 05, 2009
python-crypto vulnerability
CVE-2009-0544
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 7.10
Ubuntu 8.04 LTS
Ubuntu 8.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  python2.4-crypto                2.0.1+dfsg1-1ubuntu1.1

Ubuntu 7.10:
  python-crypto                   2.0.1+dfsg1-2ubuntu1.1

Ubuntu 8.04 LTS:
  python-crypto                   2.0.1+dfsg1-2.1ubuntu1.1

Ubuntu 8.10:
  python-crypto                   2.0.1+dfsg1-2.3ubuntu0.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

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.
