Synopsis ========
A vulnerability was discovered in util-linux, which could potentially lead to the execution of arbitrary code.
Background ==========
util-linux is a suite of Linux programs including mount and umount, programs used to mount and unmount filesystems.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/util-linux < 2.30.2-r1 >= 2.30.2-r1
Description ===========
It was discovered that the umount bash-completion as provided by util-linux does not escap mount point paths.
Impact ======
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 privileges.
Workaround ==========
Disable Bash-completion or remove "/usr/share/bash-completion/completions/umount".
Resolution ==========
All util-linux users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/util-linux-2.30.2-r1"
