GHSA-86Q4-P3XC-6M2H

Vulnerability from github – Published: 2022-05-24 17:44 – Updated: 2022-05-24 17:44

Details

The fb_unserialize function did not impose a depth limit for nested deserialization. That meant a maliciously constructed string could cause deserialization to recurse, leading to stack exhaustion. This issue affected HHVM prior to v4.32.3, between versions 4.33.0 and 4.56.0, 4.57.0, 4.58.0, 4.58.1, 4.59.0, 4.60.0, 4.61.0, 4.62.0.
