"The version of Foxit Reader installed on the remote Windows host is
prior to 6.1.4. It is, therefore, affected by a flaw in how
dynamic-link library (DLL) files are located and loaded, specifically
file imgseg.dll. The application uses a fixed path to search for this
file, and the path can include directories that may not be trusted or
under the user's control. A local attacker can exploit this issue, via
a crafted Trojan horse DLL file injected into the search path, to
execute arbitrary code with the user's privileges.");
