If the setgid bit is set for a directory, any new files created are owned by the directory's owning group, instead of the user's group. Files moved or copied from another location will not have their group ID modified.Related information See our Unix and Linux commands page for a full ...
Linux has some other permissions that are used for specific cases. Among those you can findsetuidandsetgid, which are meant for occasions when you have a program which must run as a specific user or group (usually root), but you don’t want to give elevated privileges...
Let's go back to the answer above and now explain how umask is calculated and files and directories. umask is about restricting permissions, in essence this means there are maximum permissions you can subtract from (not add to). What umask is doin...
For example, if the user is running as UID 1000 and has an entry of USER:100000:65536, Podman executes the setuid and setgid apps, /usr/bin/newuidmap and /usr/bin/newgidmap, to configure the user namespace. The user namespace then gets the following mapping:...

Security:LD_LIBRARY_PATH directories are checked first, before their actual location. This approach could be used by a malicious individual to force your application to run a malicious version of a shared library. One of the reasons why setuid/setgid executables ignore that variable is because of...
Setting 777 permissions (chmod 777) to a file or directory means that it will be readable, writable and executable by all users and may pose a huge security risk.
As discussed, the set uid bit controls file access to other users, while the setgid (GID) bit creates collaborative directories. That means any file created inside that directory is accessible to the directory's group. Hence, it allows all group members to run executable files without the owne...
