Symantec AppStream 5.2.x and Symantec Workspace Streaming (SWS) 6.1.x before 6.1 SP4 do not properly perform authentication, which allows remote Workspace Streaming servers and man-in-the-middle attackers to download arbitrary executable files onto a client system, and execute these files, via unspecified vectors.

The LaunchObj ActiveX control before 5.2.2.865 in launcher.dll in Symantec AppStream Client 5.2.x before 5.2.2 SP3 MP1 does not properly validate downloaded files, which allows remote attackers to execute arbitrary code via the installAppMgr method and unspecified other methods.
