Summary
AMD Compressonator SDK before v4.6.0 has an integer overflow in its DDS RGB888 loader (CWE-190). The overflow causes an undersized heap allocation and a later out-of-bounds read. A local attacker who gets a user to open a crafted DDS file can terminate the process or disclose limited heap memory.
