• CVE-2018-8787: Fix a potential remote code execution vulnerability in the gdi_Bitmap_Decompress function (bsc#1117964)
• CVE-2018-8788: Fix a potential remote code execution vulnerability in the nsc_rle_decode function (bsc#1117963)
• CVE-2018-8784: Fix a potential remote code execution vulnerability in the zgfx_decompress_segment function (bsc#1116708)
• CVE-2018-1000852: Fixed a remote memory access in the drdynvc_process_capability_request function (bsc#1120507)

Other issues:

• Upgraded to version 2.0.0-rc4 (FATE#326739)
• Security and stability improvements, including bsc#1103557 and bsc#1112028
• gateway: multiple fixes and improvements
• client/X11: support for rail (remote app) icons was added
• The licensing code was re-worked: Per-device licenses are now saved on the client and used on re-connect:
  WARNING: this is a change in FreeRDP behavior regarding licensing. If the old behavior is required, or no licenses should be saved use the new command line option +old-license (gh#/FreeRDP/FreeRDP#4979)
• Improved order handling - only orders that were enable during capability exchange are accepted. WARNING and NOTE: some servers do improperly send orders that weren't negotiated, for such cases the new command line option /relax-order-checks was added to disable the strict order checking. If connecting to xrdp the options /relax-order-checks and +glyph-cache are required. (gh#/FreeRDP/FreeRDP#4926)
• Fixed automount issues
• Fixed several audio and microphone related issues
• Fixed X11 Right-Ctrl ungrab feature
• Fixed race condition in rdpsnd channel server.
