CVE-2014-3622
Use-after-free vulnerability in the add_post_var function in the Posthandler component in PHP 5.6.x before 5.6.1 might allow remote attackers to execute arbitrary code by leveraging a third-party filter extension that accesses a certain ksep value.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.12%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
