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.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The libtiff packages contain a library of functions for manipulating
Tagged Image File Format (TIFF) files.

Security Fix(es) :

* Multiple flaws have been discovered in libtiff. A remote attacker
could exploit these flaws to cause a crash or memory corruption and,
possibly, execute arbitrary code by tricking an application linked
against libtiff into processing specially crafted files.
(CVE-2016-9533, CVE-2016-9534, CVE-2016-9535)

* Multiple flaws have been discovered in various libtiff tools
(tiff2pdf, tiffcrop, tiffcp, bmp2tiff). By tricking a user into
processing a specially crafted file, a remote attacker could exploit
these flaws to cause a crash or memory corruption and, possibly,
execute arbitrary code with the privileges of the user running the
libtiff tool. (CVE-2015-8870, CVE-2016-5652, CVE-2016-9540,

    in LibTIFF allows remote attackers to cause a denial of

  - A flaw was discovered in the bmp2tiff utility. By
    tricking a user into processing a specially crafted

    cause a crash or memory corruption and, possibly,
    execute arbitrary code with the privileges of the user

    tiled images with odd tile width versus image width.
    Reported as MSVR 35103, aka 'cpStripToTile
    heap-buffer-overflow.'(CVE-2016-9540)

  - tif_predict.h and tif_predict.c in libtiff 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.
    Reported as MSVR 35105, aka 'Predictor
