CVE-2017-9937 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-9937): In LibTIFF 4.0.8, there is a memory malloc failure in tif_jbig.c. A crafted TIFF document can lead to an abort resulting in a remote denial of service attack. CVE-2017-9936 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-9936): In LibTIFF 4.0.8, there is a memory leak in tif_jbig.c. A crafted TIFF document can lead to a memory leak resulting in a remote denial of service attack. CVE-2017-9935 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-9935): 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.
