Integer overflow in the 16 bit variable reference counter in PHP 4 allows context-dependent attackers to execute arbitrary code by overflowing this counter, which causes the same variable to be destroyed twice, a related issue to CVE-2007-1286.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
