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.
