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 width and precision of -1 is passed to the php_sprintf_appendstring function, it may place an internal buffer at an arbitrary memory location. This may allow an attacker to execute arbitrary code.
