Description

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.

Affected products

Andries Brouwer Util-Linux: 2.8.1_alpha, 2.8_12, 2.9i, 2.9w, 2.10f, 2.10m (+19)
