Multiple integer signedness errors in the printf function family in
PHP 4 before 4.4.5 and PHP 5 before 5.2.1 on 64 bit machines allow
context-dependent attackers to execute arbitrary code via (1) certain
negative argument numbers that arise in the php_formatted_print
function because of 64 to 32 bit truncation, and bypass a check for
the maximum allowable value; and (2) a width and precision of -1,
which make it possible for the php_sprintf_appendstring function to
place an internal buffer at an arbitrary memory location.
