Description
Files with the sgid bit set will allow anyone running these files to be temporarily assigned the group id of the file. While many system files depend on these attributes for proper operation, security problems can result if setgid is assigned to programs that allow reading and writing of files, or shell escapes. Not applicable - Not a General Purpose (GP) OS. VMware's ESXi-v5 is a multi-user kernel where all users are "administrator" with either: Administrator with Full and partial (configurable) privileges, Read-only, or No Access. In this case, the file owner, group-owner and mode(s) have no meaning.
