CVE-2017-9935 (opens in a new tab)How to fix?
Upgrade Debian:9 tiff to version 4.0.8-2+deb9u2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tiff package and not the tiff package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
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.
