Description
An out-of-bounds heap write flaw was found in GIMP's PVR image loader. When loading a crafted non-square PVR texture, pvr_decode_twiddle() can write attacker-controlled pixel data beyond the end of a correctly allocated heap buffer because the destination offset is not bounds-checked. A local attacker can exploit this by convincing a user to open a malicious PVR image, potentially causing arbitrary code execution in the file-pvr plug-in process.
