## Description

In LibTIFF 4.0.8, there is a heap-based buffer overflow in the
t2p\_write\_pdf function in tools/tiff2pdf.c. This heap overflow could lead
to different damages. For example, a crafted TIFF document can lead to an
out-of-bounds read in TIFFCleanup, an invalid free in TIFFClose or
t2p\_free, memory corruption in t2p\_readwrite\_pdf\_image, or a double free in
t2p\_free. Given these possibilities, it probably could cause arbitrary code
execution.
