Description


Sebastian Schmidt has discovered a vulnerability in Python, potentially allowing malicious people to execute arbitrary code on a vulnerable system.

The problem is that the "getaddrinfo()" function contains a boundary error in the handling of certain IPv6 responses. This can potentially be exploited by malicious people by sending a maliciously crafted response from a DNS server.

The vulnerability affects Python versions 2.2 through 2.2.2 configured without IPv6 support.


Solution:
Rebuild or update Python.
