Debian LTS Advisory ([SECURITY] [DLA 1411-1] tiff security update)

Several issues were discovered in TIFF, the Tag Image File Format library, that allowed remote attackers to cause a denial-of-service or other unspecified impact via a crafted image file. CVE-2017-11613: DoS vulnerability 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 the value of td_imagelength is set close to the amount of system memory, it will hang the system or trigger the OOM killer. CVE-2018-10963: DoS vulnerability The TIFFWriteDirectorySec() function in tif_dirwrite.c in LibTIFF allows remote attackers to cause a denial of service (assertion failure and application crash) via a crafted file, a different vulnerability than CVE-2017-13726. CVE-2018-5784: DoS vulnerability In LibTIFF, there is an uncontrolled resource consumption in the TIFFSetDirectory function of tif_dir.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tif file. This occurs because the declared number of directory entries is not validated against the actual number of directory entries. CVE-2018-7456: NULL Pointer Dereference A NULL Pointer Dereference occurs in the function TIFFPrintDirectory in tif_print.c in LibTIFF when using the tiffinfo tool to print crafted TIFF information, a different vulnerability than CVE-2017-18013. (This affects an earlier part of the TIFFPrintDirectory function that was not addressed by the CVE-2017-18013 patch.) CVE-2018-8905: Heap-based buffer overflow In LibTIFF, a heap-based buffer overflow occurs in the function LZWDecodeCompat in tif_lzw.c via a crafted TIFF file, as demonstrated by tiff2ps.
