python -- multiple vulnerabilities

Secunia reports:

Some vulnerabilities have been reported in Python, where some have
unknown impact and others can potentially be exploited by malicious
people to cause a DoS (Denial of Service) or to compromise a
vulnerable system.
Various integer overflow errors exist in core modules e.g.
stringobject, unicodeobject, bufferobject, longobject, tupleobject,
stropmodule, gcmodule, mmapmodule.
An integer overflow in the hashlib module can lead to an unreliable
cryptographic digest results.
Integer overflow errors in the processing of unicode strings can be
exploited to cause buffer overflows on 32-bit systems.
An integer overflow exists in the PyOS_vsnprintf() function on
architectures that do not have a “vsnprintf()” function.
An integer underflow error in the PyOS_vsnprintf() function when
passing zero-length strings can lead to memory corruption.
