sol35155453: Multiple LibTIFF vulnerabilities
Security Advisory
Original Publication Date: 11/08/2016
Vulnerability Description
CVE-2015-8683
The putcontig8bitCIELab function in tif_getimage.c in LibTIFF 4.0.6
allows remote attackers to cause a denial of service (out-of-bounds
read) via a packed TIFF image.
CVE-2015-8665
tif_getimage.c in LibTIFF 4.0.6 allows remote attackers to cause a
denial of service (out-of-bounds read) via the SamplesPerPixel tag in
a TIFF image.
CVE-2014-8130
** RESERVED ** This candidate has been reserved by an organization or
individual that will use it when announcing a new security problem. When
the candidate has been publicized, the details for this candidate will
be provided.
CVE-2014-8130
** RESERVED ** This candidate has been reserved by an organization or
individual that will use it when announcing a new security problem. When
the candidate has been publicized, the details for this candidate will
be provided.
CVE-2014-8127
** RESERVED ** This candidate has been reserved by an organization or
individual that will use it when announcing a new security problem. When
the candidate has been publicized, the details for this candidate will
be provided.
CVE-2014-9655
The (1) putcontig8bitYCbCr21tile function in tif_getimage.c or (2)
NeXTDecode function in tif_next.c in LibTIFF allows remote attackers to
cause a denial of service (uninitialized memory access) via a crafted
TIFF image, as demonstrated by libtiff-cvs-1.tif and libtiff-cvs-2.tif.
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, a different vulnerability than CVE-2015-8782.
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, a different
vulnerability than CVE-2015-8781.
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.
Impact
An attacker can use specially-crafted TIFF files to execute arbitrary code
with the limited privileges of the image optimization process.

Vulnerability Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only
an older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.
Mitigation
To mitigate the risk posed by this vulnerability, you can ensure that TIFF
file processing via BIG-IP AAM or WebAccelerator policies is disabled, or
ensure that TIFF files processed by BIG-IP AAM and WebAccelerator cannot
be modified by attackers.
Impact of action: Performing the suggested mitigation should not have a
negative impact on your system.

BIG-IP AAM: The Accelerating Images with Image Optimization chapter
of the BIG-IP Acceleration Implementations guide
