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

This security advisory corrects DSA 458-1 which caused some segmentation faults in gethostbyaddr with non-localhost input. This update also disables IPv6 on all architectures. 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). For the stable distribution (woody), this bug has been fixed in version 2.2.1-4.5. The testing and unstable distribution (sid) are not affected by this problem. We recommend that you update your python2.2 package.
