tif_read.c in LibTIFF 4.0.7 does not ensure that tif_rawdata is properly initialized, which might allow remote attackers to obtain sensitive information from process memory via a crafted image.
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.
