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)
