Description

PHP contains a flaw that may allow a context-dependent attacker to gain elevated privileges. The issue is due to an integer signedness error in the printf function family as used on 64 bit machines. When a negative argument number is passed to the php_formatted_print function before a 64 to 32 bit truncation, it may bypass a check for the maximum allowable value causing memory corruption. This may allow an attacker to execute arbitrary code.
