umount in util-linux 2.8 to 2.12q, 2.13-pre1, and 2.13-pre2, and other packages such as loop-aes-utils, allows local users with unmount permissions to gain privileges via the -r (remount) option, which causes the file system to be remounted with just the read-only flag, which effectively clears the nosuid, nodev, and other flags.

Security readout for executives and security teams

This is an old local privilege escalation in umount. A user who already has unmount permission could remount a filesystem read-only in a way that clears safety flags such as nosuid and nodev, potentially enabling privilege gain. Risk is mainly legacy or appliance systems still carrying affected util-linux or related packages. Exposure requires local access plus permission to unmount affected filesystems. Modern systems are unlikely exposed unless they run very old, unpatched vendor packages or embedded/appliance images derived from them. Treat as cleanup for legacy Linux/Unix exposure, not an internet emergency. Prioritize systems with local multi-user access, shared shells, appliances, or old distribution images. Mitigation focus: Check vendor advisories for util-linux or loop-aes-utils package updates.; Patch or replace affected legacy packages on supported systems.; Restrict local users allowed to mount or unmount filesystems..
