"This security advisory corrects DSA 458-2 which caused a problem in
the gethostbyaddr routine.

The original advisory said :

  Sebastian Schmidt discovered a buffer overflow bug in Python's
  getaddrinfo function, which could allow an IPv6 address, supplied by
  a remote attacker via DNS, to overwrite memory on the stack.

  This bug only exists in python 2.2 and 2.2.1, and only when IPv6
  support is disabled. The python2.2 package in Debian woody meets
  these conditions (the 'python' package does not)."
