Several vulnerabilities have been found in the TIFF library, which may result in denial of service or the execution of arbitrary code if malformed image files are processed.

The remote host is affected by the vulnerability described in GLSA-202003-25 (libTIFF: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libTIFF. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker, by enticing the user to process a specially crafted       TIFF file, could possibly cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

According to the versions of the libtiff packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - ** DISPUTED ** LibTIFF 4.0.8 has multiple memory leak     vulnerabilities, which allow attackers to cause a     denial of service (memory consumption), as demonstrated     by tif_open.c, tif_lzw.c, and tif_aux.c. NOTE: Third     parties were unable to reproduce the     issue.(CVE-2017-16232)

  - _TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in     LibTIFF through 4.0.10 mishandle Integer Overflow     checks because they rely on compiler behavior that is     undefined by the applicable C standards. This can, for     example, lead to an application crash.(CVE-2019-14973)

  - An Invalid Address dereference was discovered in     TIFFWriteDirectoryTagTransferfunction in     libtiff/tif_dirwrite.c in LibTIFF 4.0.10, affecting the     cpSeparateBufToContigBuf function in tiffcp.c.

  - The cvtClump function in the rgb2ycbcr tool in LibTIFF     4.0.6 and earlier allows remote attackers to cause a     denial of service (out-of-bounds write) by setting the     '-v' option to -1.(CVE-2016-3624)

  - The DumpModeDecode function in libtiff 4.0.6 and     earlier allows attackers to cause a denial of service     (invalid read and crash) via a crafted tiff     image.(CVE-2016-5321)

  - The rgb2ycbcr tool in LibTIFF 4.0.6 and earlier allows     remote attackers to cause a denial of service     (divide-by-zero) by setting the (1) v or (2) h     parameter to 0.(CVE-2016-3623)

  - The TIFFFdOpen function in tif_unix.c in LibTIFF 4.0.10     has a memory leak, as demonstrated by     pal2rgb.(CVE-2019-6128)

  - The TIFFWriteDirectorySec() function in tif_dirwrite.c     in LibTIFF through 4.0.9 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-2018-10963)

  - tif_getimage.c in LibTIFF through 4.0.10, as used in     GDAL through 3.0.1 and other products, has an integer     overflow that potentially causes a heap-based buffer     overflow via a crafted RGBA image, related to a     'Negative-size-param' condition.(CVE-2019-17546)

Brief introduction 

CVE-2018-17000

A NULL pointer dereference in the function _TIFFmemcmp at tif_unix.c (called from TIFFWriteDirectoryTagTransferfunction) allows an attacker to cause a denial of service through a crafted tiff file. 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).

For Debian 8 'Jessie', these problems have been fixed in version 4.0.3-12.3+deb8u8.

We recommend that you upgrade your tiff packages.
