The unserialize implementation in ext/standard/var.c in PHP 7.x before 7.0.14 allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted serialized data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-6834.

Security readout for executives and security teams

This is a PHP 7 unserialize flaw. A remote attacker who can make an application process crafted serialized data may crash the PHP process, causing denial of service. The CVE also says unspecified other impact may be possible, but the provided sources do not define it. Exposure is most likely in legacy PHP 7.x deployments before 7.0.14, especially applications that unserialize attacker-controlled or externally supplied data. The bundle does not identify specific frameworks, products, or default-exposed endpoints. Treat this as a legacy-platform remediation item, not an emergency based on the provided evidence. Prioritize internet-facing PHP 7.x systems and any application processing untrusted serialized data. Mitigation focus: Upgrade PHP 7.x deployments to 7.0.14 or a vendor-supported fixed package.; Apply relevant distribution advisories, including Red Hat or openSUSE updates where applicable.; Avoid unserializing untrusted or externally supplied data where application changes are feasible..
