CVE-2015-6831
Multiple use-after-free vulnerabilities in SPL in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 allow remote attackers to execute arbitrary code via vectors involving (1) ArrayObject, (2) SplObjectStorage, and (3) SplDoublyLinkedList,…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.06%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
