"The version of Adobe InCopy installed on the remote host is prior to 17.0.0. It is, therefore, affected by multiple
vulnerabilities as referenced in the APSB21-110 advisory.

  - Adobe InCopy version 16.4 (and earlier) is affected by a memory corruption vulnerability due to insecure
    handling of a malicious GIF file, potentially resulting in arbitrary code execution in the context of the
    current user. User interaction is required in that the victim must open a specially crafted file to
    exploit this vulnerability. (CVE-2021-43015)

  - Adobe InCopy version 16.4 (and earlier) is affected by a Null pointer dereference vulnerability when
    parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to achieve
    an application denial-of-service in the context of the current user. Exploitation of this issue requires
    user interaction in that a victim must open a malicious file. (CVE-2021-43016)

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