[GLSA-200608-28] PHP: Arbitary code execution

Vulnerability Assessment Summary
PHP: Arbitary code execution

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200608-28

The sscanf() PHP function contains an array boundary error that can be
exploited to dereference a null pointer. This can possibly permit the
bypass of the safe mode protection by executing arbitrary code.

applications making use of the sscanf() function, potentially resulting
in the execution of arbitrary code or the execution of scripted
contents in the context of the affected site.
