The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM / 22.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5205-1 advisory.

    It was discovered that Tcpreplay incorrectly handled certain specially crafted packet capture input when     processed by tcpprep. An attacker could possibly use this issue to cause a denial of service. This issue     only affected Ubuntu 18.04 ESM. (CVE-2018-13112)

    It was discovered that Tcpreplay incorrectly handled certain specially crafted packet capture input. An     attacker could possibly use this issue to cause a denial of service or expose sensitive information. This     issue only affected Ubuntu 16.04 ESM and Ubuntu 18.04 ESM. (CVE-2018-17580, CVE-2018-17582)

    It was discovered that Tcpreplay incorrectly handled certain specially crafted packet capture input. An     attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 16.04     ESM and Ubuntu 18.04 ESM. (CVE-2018-17974, CVE-2018-18407)

    It was discovered that a use-after-free existed in Tcpreplay in the tcpbridge binary. An attacker could     possibly use this issue to cause a denial of service. This issue only affected Ubuntu 16.04 ESM and Ubuntu     18.04 ESM. (CVE-2018-18408)

    It was discovered that Tcpreplay incorrectly handled certain specially crafted packet capture input. An     attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 16.04     ESM, Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2018-20552, CVE-2018-20553)

    It was discovered that a heap-based buffer over-read that existed in Tcpreplay caused an application crash     when tcprewrite or tcpreplay-edit received specially crafted packet capture input. An attacker could     possibly use this to cause a denial of service or to expose sensitive information. This issue only     affected Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2020-12740)

    It was discovered that Tcpreplay incorrectly handled certain specially crafted packet capture input when     processed by tcpprep. An attacker could possibly use this issue to cause a denial of service. This issue     only affected Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2020-24265, CVE-2020-24266)

    It was discovered that Tcpreplay incorrectly handled certain specially crafted packet capture input when     processed by tcprewrite. An attacker could possibly use this issue to cause a denial of service. This     issue only affected Ubuntu 22.04 ESM. (CVE-2022-27416)

    It was discovered that Tcpreplay did not properly manage memory under certain circumstances. If a user     were tricked into opening a specially crafted packet capture file, a remote attacker could possibly use     this issue to cause Tcpreplay crash, resulting in a denial of service, or possibly read sensitive data.
    This issue only affected Ubuntu 18.04 ESM, Ubuntu 20.04 ESM and Ubuntu 22.04 ESM. (CVE-2022-28487)
