An exploitable heap-based buffer overflow exists in the handling of TIFF images in LibTIFF's TIFF2PDF tool. A crafted TIFF document can lead to a heap-based buffer overflow resulting in remote code execution. Vulnerability can be triggered via a saved TIFF file delivered by other means.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
