"The version of Adobe Character Animator 2021 installed on the remote Windows host is prior to 4.4.2. It is, therefore,
affected by multiple vulnerabilities including the following:

  - An arbitrary code execution vulnerability exists in Adobe Character Animator. An unauthenticated, local
    attacker can exploit this to bypass authentication and execute arbitrary commands. (CVE-2021-40763,
    CVE-2021-40764, CVE-2021-40765)

  - A NULL pointer dereference flaw exists in Adobe Character Animator. An unauthenticated, local attacker can
    exploit this to cause the application to stop responding. (CVE-2021-40762, CVE-2021-40768)

  - A memory access flaw exists in Adobe Character Animator. An unauthenticated, local attacker can exploit
    this to cause the application to stop responding. (CVE-2021-40767)

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