Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Vincent Danen via Red Hat Issue Tracker reports :

A vulnerability was reported in Python's socket module, due to a
boundary error within the sock_recvfrom_into() function, which could
be exploited to cause a buffer overflow. This could be used to crash a
Python application that uses the socket.recvfrom_info() function or,
possibly, execute arbitrary code with the permissions of the user
running vulnerable Python code.

This vulnerable function, socket.recvfrom_into(), was introduced in
Python 2.5. Earlier versions are not affected by this flaw.
