CVE-2016-7133
Zend/zend_alloc.c in PHP 7.x before 7.0.10, when open_basedir is enabled, mishandles huge realloc operations, which allows remote attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact via a long pathname.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
