This update:
- Addresses an issue that could cause Messages conversations to temporarily be listed out of order
- Resolves an issue that could cause your Mac to stop responding when connected to an SMB server
The security patch notes for macOS High Sierra 10.13.3 specify 17 different security holes fixed in the update. They include a variety of kernel, low-level areas, audio, and WebKit issues, many of which can lead to a compromised Mac.
You can download the update through the Mac App Store.

Does this update also fix the problems with nvidia gt650m/750m GPUs in 2013/2014 MacBook Pros (which are supported by High Sierra)?
Basically in High Sierra these GPUs run so slowly for most OpenGL/opencl/webgl/ and metal2 functions.
Many people have downgraded to Sierra to fix the issues, everything is then back to normal.
