    USN-6644-1 fixed vulnerabilities in LibTIFF. This update provides the corresponding updates for Ubuntu
    22.04 LTS.

    Original advisory details:

    It was discovered that LibTIFF incorrectly handled certain files. If

    a user were tricked into opening a specially crafted file, an attacker

    could possibly use this issue to cause the application to crash, resulting

    in a denial of service. (CVE-2023-52356)

    It was discovered that LibTIFF incorrectly handled certain image files

    with the tiffcp utility. If a user were tricked into opening a specially

    crafted image file, an attacker could possibly use this issue to cause

    tiffcp to crash, resulting in a denial of service. (CVE-2023-6228)

    It was discovered that LibTIFF incorrectly handled certain files. If

    a user were tricked into opening a specially crafted file, an attacker

    could possibly use this issue to cause the application to consume

    resources, resulting in a denial of service. (CVE-2023-6277)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
