Python before 2.6.8, 2.7.x before 2.7.3, 3.x before 3.1.5, and 3.2.x before
3.2.3 computes hash values without restricting the ability to trigger hash
collisions predictably, which allows context-dependent attackers to cause a
denial of service (CPU consumption) via crafted input to an application
that maintains a hash table.

Notes

Author	Note
jdstrand	patch does not change the default, so the risk of backporting to python2.5 and python2.4 outweighs the benefit of adding the patch. Ubuntu 8.04 LTS who require this patch should upgrade to Ubuntu 10.04 LTS or another supported release. the patch for 3.2 on oneiric is somewhere between the upstream 3.1 and 3.2 patches. Specifically, need the Modules/_datetimemodule.c changes
