CVE-2004-0150: Debian -- Security Information -- DSA-458-3 python2.2

Buffer overflow in the getaddrinfo function in Python 2.2 before 2.2.2, when IPv6 support is disabled, allows remote attackers to execute arbitrary code via an IPv6 address that is obtained using DNS.

CVE
#debian#buffer_overflow

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).

For the stable distribution (woody), this bug has been fixed in version 2.2.1-4.6.

The testing and unstable distribution (sarge and sid) are not affected by this problem.

We recommend that you update your python2.2 packages.
