CVE-2014-8127

LibTIFF 4.0.3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted TIFF image to the (1) checkInkNamesString function in tif_dir.c in the thumbnail tool, (2) compresscontig function in tiff2bw.c in the tiff2bw tool, (3) putcontig8bitCIELab function in tif_getimage.c in the tiff2rgba tool, LZWPreDecode function in tif_lzw.c in the (4) tiff2ps or (5) tiffdither tool, (6) NeXTDecode function in tif_next.c in the tiffmedian tool, or (7) TIFFWriteDirectoryTagLongLong8Array function in tif_dirwrite.c in the tiffset tool.

LibTIFF 4.0.3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted TIFF image to the (1) checkInkNamesString function in tif_dir.c in the thumbnail tool, (2) compresscontig function in tiff2bw.c in the tiff2bw tool, (3) putcontig8bitCIELab function in tif_getimage.c in the tiff2rgba tool, LZWPreDecode function in tif_lzw.c in the (4) tiff2ps or (5) tiffdither tool, (6) NeXTDecode function in tif_next.c in the tiffmedian tool, or (7) TIFFWriteDirectoryTagLongLong8Array function in tif_dirwrite.c in the tiffset tool.

The libtiff image decoder library contains several issues that could cause the decoder to crash when reading crafted TIFF images (CVE-2014-8127, CVE-2014-8128, CVE-2014-8129, CVE-2014-8130, CVE-2014-9655, CVE-2015-1547).

The TIFFWriteDirectoryTagLongLong8Array function in tif_dirwrite.c in the tiffset tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds read) via vectors involving the ma variable (CVE-2016-3658).

They also fix:

An out-of-bound read of up to 3 bytes in readContigTilesIntoBuffer().

An out-of-bound read on some tiled images.

Segfault when specifying -r without argument (fax2tiff).

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

tiff was updated to fix six security issues found by fuzzing initiatives.

William Robinet 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. (CVE-2014-8127, CVE-2014-8128, CVE-2014-8129, CVE-2014-8130)

Paris Zoumpouloglou discovered that LibTIFF incorrectly handled certain malformed BMP images. If a user or automated system were tricked into opening a specially crafted BMP image, a remote attacker could crash the application, leading to a denial of service. (CVE-2014-9330)

Michal Zalewski 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.
