The vulnerability stems from uninitialized pixel buffers in JPEG/TGA decoders. The patches explicitly add AllocationOptions.Clean (JPEG) and replace CreateUninitialized with a constructor that initializes buffers (TGA). These changes directly address CWE-212 and CWE-226 by ensuring buffers are cleared before reuse. The affected functions are clearly identified in the commit diffs as the pre-patch buffer allocation points.
