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

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

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in LibTIFF.

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

Details:

USN-5523-1 fixed several vulnerabilities in LibTIFF. This update
provides the fixes for CVE-2022-0907, CVE-2022-0908, CVE-2022-0909,
CVE-2022-0924 and CVE-2022-22844 for Ubuntu 18.04 LTS and
Ubuntu 20.04 LTS.

Original advisory details:

  It was discovered that LibTIFF was not properly perf   orming 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 20.04 LTS:
   libtiff-opengl                  4.1.0+git191117-2ubuntu0.20.04.4
   libtiff-tools                   4.1.0+git191117-2ubuntu0.20.04.4
   libtiff5                        4.1.0+git191117-2ubuntu0.20.04.4
   libtiffxx5                      4.1.0+git191117-2ubuntu0.20.04.4

Ubuntu 18.04 LTS:
   libtiff-opengl                  4.0.9-5ubuntu0.6
   libtiff-tools                   4.0.9-5ubuntu0.6
   libtiff5                        4.0.9-5ubuntu0.6
   libtiffxx5                      4.0.9-5ubuntu0.6

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