Release time is approximately 17:00 UTC.
We don’t currently know a whole lot about the extent of this vulnerability but we do know it is serious. Some speculate it has to do with file handle invalidated on broken lock. The bug is in Samba which is a cross-platform file sharing pre-installed on your operating system. Patch is for Samba versions 4.4, 4.3 and 4.2. 4.1 version is discontinued.
We will add more information as we receive them. Please check back here frequently.
