Description Joe Orton 2007-05-15 15:51:56 UTC
Description of problem:
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.

Comment 1 Joe Orton 2007-05-15 15:53:50 UTC
The 'filter' extension is not currently included in php packages distributed by
Red Hat.
