GHSA-r9p4-q4p6-83c5 PUBLISHED CVSS 9.300000190734863 CRITICAL

Record from GitHub Advisory Database · Published May 17, 2022

The sysvshm extension for PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allows context-dependent attackers to write to arbitrary memory addresses by using an object's __sleep function to interrupt an internal call to the shm_put_var function, which triggers access of a freed resource.
