In Tencent QQ through 9.7.8.29039 and TIM through 3.4.7.22084, QQProtect.exe and QQProtectEngine.dll do not validate pointers from inter-process communication, which leads to a write-what-where condition.
Weakness
The product attempts to return a memory resource to the system, but it calls the wrong release function or calls the appropriate release function incorrectly.
