CVE-2017-13727 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-13727): There is a reachable assertion abort in the function TIFFWriteDirectoryTagSubifd() in LibTIFF 4.0.8, related to tif_dirwrite.c and a SubIFD tag. A crafted input will lead to a remote denial of service attack. CVE-2017-13726 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-13726): There is a reachable assertion abort in the function TIFFWriteDirectorySec() in LibTIFF 4.0.8, related to tif_dirwrite.c and a SubIFD tag. A crafted input will lead to a remote denial of service attack. CVE-2017-12944 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-12944): The TIFFReadDirEntryArray function in tif_read.c in LibTIFF 4.0.8 mishandles memory allocation for short files, which allows remote attackers to cause a denial of service (allocation failure and application crash) in the TIFFFetchStripThing function in tif_dirread.c during a tiff2pdf invocation. CVE-2017-11613 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-11613): In LibTIFF 4.0.8, there is a denial of service vulnerability in the TIFFOpen function. A crafted input will lead to a denial of service attack. During the TIFFOpen process, td_imagelength is not checked. The value of td_imagelength can be directly controlled by an input file. In the ChopUpSingleUncompressedStrip function, the _TIFFCheckMalloc function is called based on td_imagelength. If we set the value of td_imagelength close to the amount of system memory, it will hang the system or trigger the OOM killer. CVE-2017-10688 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-10688): In LibTIFF 4.0.8, there is a assertion abort in the TIFFWriteDirectoryTagCheckedLong8Array function in tif_dirwrite.c. A crafted input will lead to a remote denial of service attack.
