Description paul boin 2007-05-07 15:14:31 UTC
Like the other PHP bugs, this on is mentioned in 230556, but not explicitly
closed and documented in any errata that I can find.

-------------------------------------------------------------------

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.
