Description

A buffer overflow in python 2.2's getaddrinfo() function was discovered by Sebastian Schmidt. If python 2.2 is built without IPv6 support, an attacker could configure their name server to let a hostname resolve to a special IPv6 address, which could contain a memory address where shellcode is placed. This problem does not affect python versions prior to 2.2 or versions 2.2.2+, and it also doesn't exist if IPv6 support is enabled.

The updated packages have been patched to correct the problem. Thanks to Sebastian for both the discovery and patch.
