CVE-2016-1904
Multiple integer overflows in ext/standard/exec.c in PHP 7.x before 7.0.2 allow remote attackers to cause a denial of service or possibly have unspecified other impact via a long string to the (1) php_escape_shell_cmd or (2) php_escape_shell_arg…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
