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

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

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- 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 the calculation
of data that would eventually be used as a reference for bound-checking
operations. An attacker could possibly use this issue to cause a denial of
service or to expose sensitive information. This issue only affected Ubuntu
18.04 LTS. (CVE-2020-19131)

It was discovered that LibTIFF was not properly terminating a function
execution when processing incorrect data. An attacker could possibly use
this issue to cause a denial of service or to expose sensitive information.
This issue only affected Ubuntu 18.04 LTS. (CVE-2020-19144)

It was discovered that LibTIFF did not properly manage memory under certain
circumstances. If a user were tricked into opening a specially crafted TIFF
file using tiffinfo tool, an attacker could possibly use this issue to
cause a denial of service. This issue only affected Ubuntu 20.04 LTS and
Ubuntu 22.04 LTS. (CVE-2022-1354)

It was discovered that LibTIFF did not properly manage memory under certain
circumstances. If a user were tricked into opening a specially crafted TIFF
file using tiffcp tool, an attacker could possibly use this issue to     
cause a denial of service. (CVE-2022-1355)

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 behaviour situation via a specially crafted file. An
attacker could possibly use this issue to cause a denial of service.
(CVE-2022-2056, CVE-2022-2057, CVE-2022-2058)
