These are all security issues fixed in the libtiff-devel-32bit-4.3.0-1.3 package on the GA media of openSUSE Tumbleweed.

This update for tiff to version 4.0.8 fixes a several bugs and security issues:

These security issues were fixed:

• CVE-2017-7595: The JPEGSetupEncode function allowed remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted image (bsc#1033127).
• CVE-2016-10371: The TIFFWriteDirectoryTagCheckedRational function allowed remote attackers to cause a denial of service (assertion failure and application exit) via a crafted TIFF file (bsc#1038438).
• CVE-2017-7598: Error in tif_dirread.c allowed remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted image (bsc#1033118).
• CVE-2017-7596: Undefined behavior because of floats outside their expected value range, which allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image (bsc#1033126).
• CVE-2017-7597: Undefined behavior because of floats outside their expected value range, which allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image (bsc#1033120).

• CVE-2017-7601: Because of a shift exponent too large for 64-bit type long undefined behavior was caused, which allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image (bsc#1033111).
• CVE-2017-7602: Prevent signed integer overflow, which allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image (bsc#1033109).
• CVE-2017-7592: The putagreytile function had a left-shift undefined behavior issue, which might allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image (bsc#1033131).
• CVE-2017-7593: Ensure that tif_rawdata is properly initialized, to prevent remote attackers to obtain sensitive information from process memory via a crafted image (bsc#1033129).
• CVE-2017-7594: The OJPEGReadHeaderInfoSecTablesDcTable function allowed remote attackers to cause a denial of service (memory leak) via a crafted image (bsc#1033128).
• CVE-2017-9403: Prevent memory leak in function TIFFReadDirEntryLong8Array, which allowed attackers to cause a denial of service via a crafted file (bsc#1042805).

These various other issues were fixed:

• Fix uint32 overflow in TIFFReadEncodedStrip() that caused an integer division by zero. Reported by Agostino Sarubbo.
• fix heap-based buffer overflow on generation of PixarLog / LUV compressed files, with ColorMap, TransferFunction attached and nasty plays with bitspersample. The fix for LUV has not been tested, but suffers from the same kind of issue of PixarLog.
• modify ChopUpSingleUncompressedStrip() to instanciate compute ntrips as TIFFhowmany_32(td->td_imagelength, rowsperstrip), instead of a logic based on the total size of data. Which is faulty is the total size of data is not sufficient to fill the whole image, and thus results in reading outside of the StripByCounts/StripOffsets arrays when using TIFFReadScanline()
• make OJPEGDecode() early exit in case of failure in OJPEGPreDecode(). This will avoid a divide by zero, and potential…

(bsc#987351 bsc#984808 bsc#984831)

It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.
