The AutoCAD Civil 3D 2017.1.2 Security Fix is available via the Autodesk Desktop App or via download from the Autodesk subscription site.
The Hotfix requires access to the original AutoCAD Civil 3D 2017 and Civil 3D 2017 Update 1 install resources and installation.
AutoCAD Civil 3D 2017.1.2 Security Fix
This security fix updates the zlib library from versions 1.2.5 and 1.2.8 to version 1.2.11.
This security fix is provided because the inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving left shifts of negative integers.
