A vulnerability was found in the libtiff library. Using a thumbnail command on a maliciously crafted image could cause the application to crash.

Vulnerable code:

/libtiff/tools/thumbnail.c:525
523  for (y = 0; y < nrows; y++) {
524      const uint8* src = rows[y] + off;
525      acc += bits[*src++ & mask0];
