This vulnerability can be triggered by the executable tiffcp. CVE-2018-19210 There is a NULL pointer dereference in the TIFFWriteDirectorySec function in tif_dirwrite.c that will lead to a denial of service attack, as demonstrated by tiffset. CVE-2019-7663 An Invalid Address dereference was discovered in TIFFWriteDirectoryTagTransferfunction in libtiff/tif_dirwrite.c, affecting the cpSeparateBufToContigBuf function in tiffcp.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tiff file. We believe this is the same as CVE-2018-17000 (above).
