Title: util-linux: User-assisted execution of arbitrary code (GLSA 201803-02)
Exploitable: local, remote
A vulnerability was discovered in util-linux, which could
potentially lead to the execution of arbitrary code.
util-linux is a suite of Linux programs including mount and umount,
programs used to mount and unmount filesystems.
Vulnerable: < 2.30.2-r1
Unaffected: >= 2.30.2-r1
Architectures: All supported architectures
It was discovered that the umount bash-completion as provided by
util-linux does not escap mount point paths.
An attacker controlling a volume label could entice a user with
privileges to mount/umount filesystems to use umount command with auto
completion, possibly resulting in execution of arbitrary code with root
Disable Bash-completion or remove
All util-linux users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/util-linux-2.30.2-r1"
