> 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 vulnerability is caused due to incorrect handling of UTF32/UCS-4
> encoded strings within the "repr()" function. If an application uses
> the "repr()" function to process attacker supplied data, this can
> potentially be exploited to execute arbitrary code.
> 
> SOLUTION:
> Update to version 2.5.
