## Description

Buffer underflow in the PHP\_FILTER\_TRIM\_DEFAULT macro in the filtering
extension (ext/filter) in PHP 5.2.0 allows context-dependent attackers to
execute arbitrary code by calling filter\_var with certain modes such as
FILTER\_VALIDATE\_INT, which causes filter to write a null byte in whitespace
that precedes the buffer.
