affected by multiple vulnerabilities as referenced in the USN-7983-1 advisory.

    David Leadbeater discovered that containerd incorrectly set certain directory path permissions. An
    attacker could possibly use this issue to achieve unauthorised access to the files. (CVE-2024-25621)

    It was discovered that containerd did not properly handle the execution of the goroutine of container
    attach. An attacker could possibly use this issue to cause a denial of service. (CVE-2025-64329)

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.");
