An integer overflow flaw was found in GIMP's PVR image loader. When a user opens a crafted PVR image, unchecked multiplication of attacker-controlled dimensions in pvr_decode_rect() can result in an undersized heap allocation followed by an out-of-bounds read. This may disclose adjacent heap contents through the decoded image or crash the file-pvr plug-in.
