This update was imported from the SUSE:SLE-12:Update update project.

Multiple vulnerabilities have been discovered in the libtiff library and the included tools tiff2rgba, rgb2ycbcr, tiffcp, tiffcrop, tiff2pdf and tiffsplit, which may result in denial of service, memory disclosure or the execution of arbitrary code.

There were additional vulnerabilities in the tools bmp2tiff, gif2tiff, thumbnail and ras2tiff, but since these were addressed by the libtiff developers by removing the tools altogether, no patches are available and those tools were also removed from the tiff package in Debian stable. The change had already been made in Debian stretch before and no applications included in Debian are known to rely on these scripts.
If you use those tools in custom setups, consider using a different conversion/thumbnailing tool.

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

  - Off-by-one error in the t2p_readwrite_pdf_image_tile     function in tools/tiff2pdf.c in LibTIFF 4.0.7 allows     remote attackers to have unspecified impact via a     crafted image.(CVE-2016-10094)

  - Integer overflow in tools/tiffcp.c in LibTIFF 4.0.7     allows remote attackers to have unspecified impact via     a crafted image, which triggers a heap-based buffer     overflow.(CVE-2016-10093)

  - LibTIFF version 4.0.7 is vulnerable to a heap buffer     overflow in the tools/tiffcp resulting in DoS or code     execution via a crafted BitsPerSample     value.(CVE-2017-5225)

  - Integer overflow in the writeBufferToSeparateStrips     function in tiffcrop.c in LibTIFF before 4.0.7 allows     remote attackers to cause a denial of service     (out-of-bounds read) via a crafted tif     file.(CVE-2016-9532)

  - The TIFFReadRawStrip1 and TIFFReadRawTile1 functions in     tif_read.c in libtiff before 4.0.7 allows remote     attackers to cause a denial of service (crash) or     possibly obtain sensitive information via a negative     index in a file-content buffer.(CVE-2016-6223)

Version 4.0.2-6+deb7u7 introduced changes that resulted in libtiff being unable to write out tiff files when the compression scheme in use relies on codec-specific TIFF tags embedded in the image.

This problem manifested itself with errors like those: $ tiffcp -r 16
-c jpeg sample.tif out.tif _TIFFVGetField: out.tif: Invalid tag 'Predictor' (not supported by codec). _TIFFVGetField: out.tif: Invalid tag 'BadFaxLines' (not supported by codec). tiffcp:
tif_dirwrite.c:687: TIFFWriteDirectorySec: Assertion `0' failed.

For Debian 7 'Wheezy', these problems have been fixed in version 4.0.2-6+deb7u10.

We recommend that you upgrade your tiff packages.

  - Heap-based buffer overflow in the loadImage function in     the tiffcrop tool in LibTIFF 4.0.6 and earlier allows     remote attackers to cause a denial of service     (out-of-bounds write) or execute arbitrary code via a     crafted TIFF image with zero tiles.(CVE-2016-3991)

  - Heap-based buffer overflow in the horizontalDifference8     function in tif_pixarlog.c in LibTIFF 4.0.6 and earlier     allows remote attackers to cause a denial of service     (crash) or execute arbitrary code via a crafted TIFF     image to tiffcp.(CVE-2016-3990)

  - LibTIFF 4.0.3 allows remote attackers to cause a denial     of service (out-of-bounds write) or possibly have     unspecified other impact via a crafted TIFF image, as     demonstrated by failure of tif_next.c to verify that     the BitsPerSample value is 2, and the     t2p_sample_lab_signed_to_unsigned function in     tiff2pdf.c.(CVE-2014-8129)

  - The LZW decompressor in the gif2tiff tool in libtiff     4.0.3 and earlier allows context-dependent attackers to     cause a denial of service (out-of-bounds write and     crash) or possibly execute arbitrary code via a crafted     GIF image.(CVE-2013-4244)

  - The _TIFFVGetField function in tif_dirinfo.c in LibTIFF     4.0.6 and earlier allows remote attackers to cause a     denial of service (out-of-bounds write) or execute     arbitrary code via a crafted TIFF image.(CVE-2016-3632)

  - The NeXTDecode function in tif_next.c in LibTIFF allows     remote attackers to cause a denial of service     (uninitialized memory access) via a crafted TIFF image,     as demonstrated by libtiff5.tif.(CVE-2015-1547)

  - In LibTIFF 4.0.9, 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-2018-19210)

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

  - 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. Remote     attackers could leverage this vulnerability to cause a     denial-of-service via a crafted tiff file. This is     different from CVE-2018-12900.(CVE-2019-7663)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Version 3.9.6-11+deb7u1 and 3.9.6-11+deb7u2 introduced changes that resulted in libtiff writing out invalid tiff files when the compression scheme in use relies on codec-specific TIFF tags embedded in the image.

For Debian 7 'Wheezy', these problems have been fixed in version 3.9.6-11+deb7u3.

We recommend that you upgrade your tiff3 packages.
