An application that implements the IMallocSpy debugging interface may experience heap corruption after you install security update 873333

View products that this article applies to.

Symptoms

After you install security update 873333, a component's heap may be corrupted when you use Component Object Model (COM) application programming interfaces (APIs).

↑ Back to the top

Cause

This problem occurs when a component uses CoRegisterMallocSpy to register the IMallocSpy debugging interface. When a pointer that does not point to the start of the heap block is returned to the heap, the heap is corrupted.

Some paths in COM APIs call the IMallocSpy::PreAlloc and IMallocSpy::PostAlloc methods without calling the corresponding free methods. If pointer adjustments are made in PostAlloc, the pointer that is returned to the heap will not be valid. Therefore, the heap is corrupted.
