Hi, the following vulnerability was published for tiff, using severity grave for now since I'm not sure code execution can be ruled out. CVE-2017-9935[0]: | 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. In the upstream bugtracker the reporter has provided his reproducers which can be used later on to verfiy a fix as well with the given testcases. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
