CVE-2016-9273

tiffsplit in libtiff 4.0.6 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted file, related to changing td_nstrips in TIFF_STRIPCHOP mode.

tiffsplit in libtiff 4.0.6 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted file, related to changing td_nstrips in TIFF_STRIPCHOP mode.

A read outside of array in tiffsplit (or other utilities using TIFFNumberOfStrips()) (CVE-2016-9273).

A potential read outside buffer in _TIFFPrintField() (CVE-2016-9297).

Multiple uint32 overflows in writeBufferToSeparateStrips(), writeBufferToContigTiles() and writeBufferToSeparateTiles() that could cause heap buffer overflows (CVE-2016-9532).

These are all security issues fixed in the libtiff-devel-32bit-4.0.7-1.1 package on the GA media of openSUSE Tumbleweed.

The tiff library and tools were updated to version 4.0.7 fixing various bug and security issues.

This update for tiff fixes the following issues:

Security issues fixed:

• CVE-2018-18661: Fixed NULL pointer dereference in the function LZWDecode in the file tif_lzw.c (bsc#1113672).
• CVE-2018-12900: Fixed heap-based buffer overflow in the cpSeparateBufToContigBuf (bsc#1099257).
• CVE-2017-9147: Fixed invalid read in the _TIFFVGetField function in tif_dir.c, that allowed remote attackers to cause a DoS via acrafted TIFF file (bsc#1040322).
• CVE-2017-9117: Fixed BMP images processing that was verified without biWidth and biHeight values (bsc#1040080).
• CVE-2017-17942: Fixed issue in the function PackBitsEncode that could have led to a heap overflow and caused a DoS (bsc#1074186).
• CVE-2016-9273: Fixed heap-based buffer overflow issue (bsc#1010163).
• CVE-2016-5319: Fixed heap-based buffer overflow in PackBitsEncode (bsc#983440).
• CVE-2016-3621: Fixed out-of-bounds read in the bmp2tiff tool (lzw packing) (bsc#974448).
• CVE-2016-3620: Fixed out-of-bounds read in the bmp2tiff tool (zip packing) (bsc#974447)
• CVE-2016-3619: Fixed out-of-bounds read in the bmp2tiff tool (none packing) (bsc#974446)
• CVE-2015-8870: Fixed integer overflow in tools/bmp2tiff.c that allowed remote attackers to causea DOS (bsc#1014461).

Non-security issues fixed:

• asan_build: build ASAN included
• debug_build: build more suitable for debugging

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.
