Security database references:

In Mitre's CVE dictionary: CVE-2007-5191.

More information:

It was discovered that util-linux, miscellaneous system utilities, didn't drop privileged user and group permissions in the correct order in the mount and umount commands. This could potentially allow a local user to gain additional privileges.

For the old stable distribution (sarge), this problem has been fixed in version 2.12p-4sarge2.

For the stable distribution (etch), this problem has been fixed in version 2.12r-19etch1.

We recommend that you upgrade your util-linux package.
