tiff vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 ESM
- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in LibTIFF.

Software Description:
- tiff: Tag Image File Format (TIFF) library

Details:

It was discovered that LibTIFF was not properly performing checks to
guarantee that allocated memory space existed, which could lead to a
NULL pointer dereference via a specially crafted file. An attacker
could possibly use this issue to cause a denial of service.
(CVE-2022-0907, CVE-2022-0908)

It was discovered that LibTIFF was not properly performing checks to
avoid division calculations where the denominator value was zero,
which could lead to an undefined behavior situation via a specially
crafted file. An attacker could possibly use this issue to cause a
denial of service. (CVE-2022-0909)

It was discovered that LibTIFF was not properly performing bounds
checks, which could lead to an out-of-bounds read via a specially
crafted file. An attacker could possibly use this issue to cause a
denial of service or to expose sensitive information. (CVE-2022-0924)

It was discovered that LibTIFF was not properly performing the
calculation of data that would eventually be used as a reference for
bounds checking operations, which could lead to an out-of-bounds
read via a specially crafted file. An attacker could possibly use
this issue to cause a denial of service or to expose sensitive
information. (CVE-2020-19131)

It was discovered that LibTIFF was not properly terminating a
function execution when processing incorrect data, which could lead
to an out-of-bounds read via a specially crafted file. An attacker
could possibly use this issue to cause a denial of service or to
expose sensitive information. (CVE-2020-19144)

It was discovered that LibTIFF was not properly performing checks
when setting the value for data later used as reference during memory
access, which could lead to an out-of-bounds read via a specially
crafted file. An attacker could possibly use this issue to cause a
denial of service or to expose sensitive information.
(CVE-2022-22844)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 ESM:
   libtiff-opengl                  4.0.6-1ubuntu0.8+esm2
   libtiff-tools                   4.0.6-1ubuntu0.8+esm2
   libtiff5                        4.0.6-1ubuntu0.8+esm2
   libtiffxx5                      4.0.6-1ubuntu0.8+esm2

Ubuntu 14.04 ESM:
   libtiff-opengl                  4.0.3-7ubuntu0.11+esm2
   libtiff-tools                   4.0.3-7ubuntu0.11+esm2
   libtiff5                        4.0.3-7ubuntu0.11+esm2
   libtiffxx5                      4.0.3-7ubuntu0.11+esm2

In general, a standard system update will make all the necessary changes.
