Discussion

PHP array_pad() Integer Overflow Memory Corruption Vulnerability

A vulnerability has been reported in PHP. The problem occurs in the array_pad() function and may allow an attacker to corrupt memory.

Further details of this vulnerability are currently unknown. This BID will be updated as more information becomes available.
