"The version of Adobe Creative Cloud Desktop installed on the remote
Windows host is prior to 3.7.0.272. It is, therefore, affected by
multiple vulnerabilities :

  - An untrusted search path vulnerability exists in the
    installer due to looking for specific files or libraries
    in the current working directory which may not be
    trusted or under user control. A local attacker can
    exploit this, via a specially crafted library (DLL)
    file, to inject and execute arbitrary code in the
    context of the current user. (CVE-2016-4157)

  - An unquoted search path vulnerability exists in
    AdobeUpdateService.exe that allows a local attacker to
    inject and execute arbitrary code via an executable in
    the %SYSTEMDRIVE% directory. (CVE-2016-4158)

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