The remote Ubuntu 18.04 ESM / 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6449-1 advisory.

    It was discovered that FFmpeg incorrectly managed memory resulting

    in a memory leak. An attacker could possibly use this issue to cause a denial of service via application     crash. This issue only

    affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-22038)

    It was discovered that FFmpeg incorrectly handled certain input files,

    leading to an integer overflow. An attacker could possibly use this issue to cause a denial of service via     application crash. This issue only

    affected Ubuntu 20.04 LTS. (CVE-2020-20898, CVE-2021-38090,

    CVE-2021-38091, CVE-2021-38092, CVE-2021-38093, CVE-2021-38094)

    It was discovered that FFmpeg incorrectly managed memory, resulting in a memory leak.

    If a user or automated system were tricked into

    processing a specially crafted input file, a remote attacker could possibly use this issue to cause a     denial of service, or execute

    arbitrary code. (CVE-2022-48434)
