Mandrake Linux Security Advisory : util-linux (MDKSA-2005:167)

This script is Copyright (C) 2005-2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandrake Linux host is missing one or more security
updates.

Description :

David Watson disovered that the umount utility, when using the '-r'
cpmmand, could remove some restrictive mount options such as 'nosuid'.
IF /etc/fstab contained user-mountable removable devices that
specified nosuid, a local attacker could exploit this flaw to execute
arbitrary programs with root privileges by calling 'umount -r' on a
removable device.

The updated packages have been patched to ensure that '-r' can only be
called by the root user.

Solution :

Update the affected losetup, mount and / or util-linux packages.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
