Description

PHP contains a flaw that may allow a malicious user to access arbitrary memory addresses. The issue is due to the shared memory (shmop) function failing to verify if the type of resource supplied is a shmop resource. By using other types of resources it is possible to read and write to shared memory addresses resulting in a loss of integrity and/or availability.
