Python -- buffer overflow in socket.recvfrom_into()

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.
