Description

Package : tiff3 Version : 3.9.6-11+deb7u4 CVE ID : CVE-2015-8781 CVE-2015-8782 CVE-2015-8783 CVE-2015-8784 CVE-2016-9533 CVE-2016-9534 CVE-2016-9535

tiff3 is affected by multiple issues that can result at least in denial of services of applications using libtiff4. Crafted TIFF files can be provided to trigger: abort() calls via failing assertions, buffer overruns (both in read and write mode).

CVE-2015-8781

tif_luv.c in libtiff allows attackers to cause a denial of service
(out-of-bounds write) via an invalid number of samples per pixel in a
LogL compressed TIFF image.

CVE-2015-8782

tif_luv.c in libtiff allows attackers to cause a denial of service
(out-of-bounds writes) via a crafted TIFF image.

CVE-2015-8783

tif_luv.c in libtiff allows attackers to cause a denial of service
(out-of-bounds reads) via a crafted TIFF image.

CVE-2015-8784

The NeXTDecode function in tif_next.c in LibTIFF allows remote
attackers to cause a denial of service (out-of-bounds write) via a
crafted TIFF image.

CVE-2016-9533

tif_pixarlog.c in libtiff 4.0.6 has out-of-bounds write
vulnerabilities in heap allocated buffers.

CVE-2016-9534

tif_write.c in libtiff 4.0.6 has an issue in the error code path of
TIFFFlushData1() that didn't reset the tif_rawcc and tif_rawcp
members.

CVE-2016-9535

tif_predict.h and tif_predict.c in libtiff 4.0.6 have assertions
that can lead to assertion failures in debug mode, or buffer
overflows in release mode, when dealing with unusual tile size
like YCbCr with subsampling.

For Debian 7 "Wheezy", these problems have been fixed in version 3.9.6-11+deb7u4.

We recommend that you upgrade your tiff3 packages.
