Sandboxie-Plus v0.5.4

Urgent security fixes (thanks @diversenok)

Build 5.46.0 resolves many box isolation issues some of them critical  that could allow rogue applications to escape the sandbox. It is highly  advised to upgrade quickly to the new builds. For further details  please review the change log below.

If you have issues with an update installation, just uninstall the  previous version keeping the sandboxie.ini and reinstall the new build.

Release Changelog

Added

• Sandboxie now strips particularly problematic privileges from sandboxed system tokens
  -- with those a process could atempt to bypass the sandbox isolation (thanks Diversenok)
  -- old legacy behavior can be enabled with "StripSystemPrivileges=n" (absolutely NOT Recommended)
• added new isolation options "ClosePrintSpooler=y" and "OpenSmartCard=n"
  -- those resources are open by default but for a hardened box its desired to close them
• added print spooler filter to prevent printers from being set up outside the sandbox
  -- the filter can be disabled with "OpenPrintSpooler=y"
• added overwrite prompt when recovering an already existing file
• added "StartProgram=", "StartService=" and "AutoExec=" options to the SandMan UI
• added more compatybility templates (thanks isaak654)

Changed

• Changed Emulated SCM behavior, boxed services are no longer by default started as boxed system
  -- use "RunServicesAsSystem=y" to enable the old legacy behavior
  -- Note: sandboxed services with a system token are still sandboxed and restricted
  -- However not granting them a system token in the first place removes possible exploit vectors
  -- Note: this option is not compatible with "ProtectRpcSs=y" and takes precedence!
