Description

PHP's ext/filter causes a libpcre recursion crash in email address validation. This happens when a string to validate is of an unusual long length.

The report mentions a limit of 1000 characters on a FreeBSD system (PHP 5.2.14).

X-Reference: #2010092410000017
Reported by: Bjoern Pedersen

Confirmed by PHP Security Team. Claimed to be an expected behaviour.
