  - Creation of a temporary file in a directory with incorrect permissions allows an authenticated, local
    attacker to execute arbitrary code. (CVE-2021-43017)

  - Improper access control allows an unauthenticated, local attacker to escalate privileges. (CVE-2021-43019)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
