installed that are affected by multiple vulnerabilities as referenced in the USN-7225-1 advisory.

    It was discovered that HTMLDOC incorrectly handled memory in the image_set_mask, git_read_lzw,
    write_header and write_node functions, 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. This issue only affected
    Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2022-0137, CVE-2022-24191,
    CVE-2022-34033, CVE-2022-34035)

    It was discovered that HTMLDOC incorrectly handled memory in the gif_get_code function, which could lead
    to a segmentation fault. If a user or application were tricked into opening a crafted GIF file, an
    attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04
    LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2022-0534)

    It was discovered that HTMLDOC did not perform proper bounds checks on image dimensions when loading JPEG
    images, which could lead to a buffer overflow. If a user or application were tricked into opening a
    crafted JPEG image, an attacker could possibly use this issue to cause a denial of service. This issue
    only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.
    (CVE-2022-27114)

    It was discovered that HTMLDOC incorrectly handled memory in the pdf_write_names function, which could
    lead to a heap buffer overflow. If a user or application were tricked into opening a specially crafted
    file, an attacker could possibly use this issue to cause a denial of service or leak sensitive
    information. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04
    LTS and Ubuntu 22.04 LTS. (CVE-2022-28085)

    It was discovered that HTMLDOC could be made to write out of bounds when attempting to strip whitespace.
    An attacker could use this issue to cause a denial of service or execute arbitrary code. (CVE-2024-45508)

    It was discovered that HTMLDOC incorrectly handled memory in the parse_pre function, which could lead to a
    heap buffer overflow. If a user or application were tricked into opening a specially crafted file, an
    attacker could possibly use this issue to cause a denial of service or execute arbitrary code.
