CVE-2017-11628: Buffer Overflow

First published: Thu Jul 06 2017(Updated: )

A stack buffer overflow exists in the latest stable release of PHP-7.1.5 and PHP-5.6.30 in PHP INI parsing API, which may accept network / local filesystem input. On malformed inputs, a stack buffer overflow in zend_ini_do_op() could write 1-byte off a fixed size stack buffer. On installations with the stack smashing mitigation, this would cause an immediate DoS; upto optimization levels, build options and stack buffer overflow mitigations, this vulnerability may allow corrupting other local variables or the frame pointer, potentially allows remotely executing code.
