Debian Security Advisory

DSA-1450-1 util-linux -- programming error

Date Reported:

05 Jan 2008

Affected Packages:

util-linux

Vulnerable:

Yes

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-19etch4.

We recommend that you upgrade your util-linux package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
