http://secunia.com/advisories/22276/

CRITICAL:
Moderately critical

IMPACT:

DESCRIPTION:
A vulnerability has been reported in Python, which can be exploited
by malicious people to cause a DoS (Denial of Service) and
potentially compromise a vulnerable system.

the "repr()" function to process attacker supplied data, this can
potentially be exploited to execute arbitrary code.
