Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Python 2.5.2 and earlier allows context-dependent attackers to execute arbitrary code via multiple vectors that cause a negative size value to be provided to the PyString_FromStringAndSize function, which allocates less memory than expected when assert() is disabled and triggers a buffer overflow.


Remediation

Install update from vendor's website.
