SafeSetID is an LSM module that gates the setid family of syscalls to
|
|
|
|
|
restrict UID/GID transitions from a given UID/GID to only those
|
|
|
|
|
approved by a system-wide whitelist. These restrictions also prohibit
|
|
|
|
|
the given UIDs/GIDs from obtaining auxiliary privileges associated
|
|
|
|
|
with CAP_SET{U/G}ID, such as allowing a user to set up user namespace
|
|
|
|
|
UID mappings.
