Last modified

CVE-2007-1453 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 9.52% chance of exploitation in the next 30 days.
