Details

It was discovered that LibTIFF incorrectly handled certain malformed
images. If a user or automated system were tricked into opening a
specially crafted image, a remote attacker could crash the application,
leading to a denial of service, or possibly execute arbitrary code with
user privileges. This issue was only fixed in Ubuntu 14.04 ESM.
(CVE-2019-14973, CVE-2019-17546, CVE-2020-35523, CVE-2020-35524,
CVE-2022-3970)

It was discovered that LibTIFF was incorrectly acessing a data structure
when processing data with the tiffcrop tool, which could lead to a heap
buffer overflow. An attacker could possibly use this issue to cause a
denial of service or execute arbitrary code. (CVE-2022-48281)
