The remote host is missing an update to python2.2 announced via advisory DSA 458-1.

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). For the stable distribution (woody), this bug has been fixed in version 2.2.1-4.3. The unstable distribution (sid) is not affected by this bug. We recommend that you update your python2.2 package.
