Vulnerability CVE-2008-1887

Published: 2008-04-18 Modified: 2012-02-12

Description:

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.
