The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6544-1 advisory.

    It was discovered that GNU binutils incorrectly handled certain COFF files. An attacker could possibly use     this issue to cause a crash or execute arbitrary code. This issue only affected Ubuntu 14.04 LTS.
    (CVE-2022-38533)

    It was discovered that GNU binutils was not properly performing bounds checks in several functions, which     could lead to a buffer overflow. An attacker could possibly use this issue to cause a denial of service,     expose sensitive information or execute arbitrary code. This issue only affected Ubuntu 20.04 LTS and     Ubuntu 22.04 LTS.

    (CVE-2022-4285, CVE-2020-19726, CVE-2021-46174)

    It was discovered that GNU binutils contained a reachable assertion, which could lead to an intentional     assertion failure when processing certain crafted DWARF files. An attacker could possibly use this issue     to cause a denial of service. This issue only affected Ubuntu 20.04 LTS

    and Ubuntu 22.04 LTS. (CVE-2022-35205)
