Title:	Debian: Security Advisory (DSA-4134-1)
Summary:	The remote host is missing an update for the Debian 'util-linux' package(s) announced via the DSA-4134-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'util-linux' package(s) announced via the DSA-4134-1 advisory. Vulnerability Insight: Bjorn Bosselmann discovered that the umount bash completion from util-linux does not properly handle embedded shell commands in a mountpoint name. An attacker with rights to mount filesystems can take advantage of this flaw for privilege escalation if a user (in particular root) is tricked into using the umount completion while a specially crafted mount is present. For the stable distribution (stretch), this problem has been fixed in version 2.29.2-1+deb9u1. We recommend that you upgrade your util-linux packages. For the detailed security status of util-linux please refer to its security tracker page at: [link moved to references] Affected Software/OS: 'util-linux' package(s) on Debian 9. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
