Discussion

PHP EXT/Filter Function Remote Buffer Overflow Vulnerability

PHP is prone to a remote buffer-overflow vulnerability because the application fails to perform boundary checks before copying user-supplied data to insufficiently sized memory buffers.

An attacker can exploit this issue to execute arbitrary machine code in the context of the affected webserver. Failed exploit attempts will likely crash the webserver, denying service to legitimate users.

PHP 5.2.0 is reported vulnerable; other versions may also be affected.

This issue was originally reported as an unspecified vulnerability in BID 22496 (PHP Version 5.2.0 and Prior Multiple Vulnerabilities). Due to the availability of more details, this issue is being assigned a new BID.
