Critical severity, CVSS 9.8. EPSS: 41.6% chance of exploitation in the next 30 days.

The SplObjectStorage unserialize implementation in ext/spl/spl_observer.c in PHP before 7.0.12 does not verify that a key is an object, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized memory access) via crafted serialized data.

Affected products

• Netapp Clustered Data Ontap: affected versions not specified
• PHP PHP: from 7.0.0, before 7.0.11 (fixed in 7.0.11)
