Multiple integer overflows in the opj_tcd_init_tile function in tcd.c in OpenJPEG, as used in PDFium in Google Chrome before 52.0.2743.116, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted JPEG 2000 data.
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.
