| Package | Affected versions | Patched versions |
|---|---|---|
| php | ≥ 7.0.0, < 7.0.11 | 7.0.11 |
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.
