SCO Security Advisory

Subject: OpenLinux: mgetty caller ID buffer overflow and spool perm vulnerabilities
Advisory number: CSSA-2003-021.0
Issue date: 2003 May 13
Cross reference:
__________________________________________________ ____________________________


1. Problem Description

mgetty will overflow an internal buffer if the caller name
reported by the modem is too long.

The faxspool spooling directory used for outgoing faxes was
world-writable.


2. Vulnerable Supported Versions

System Package
----------------------------------------------------------------------

OpenLinux 3.1.1 Server prior to mgetty-1.1.22_Aug17-13.i386.rpm

OpenLinux 3.1.1 Workstation prior to mgetty-1.1.22_Aug17-13.i386.rpm


3. Solution

The proper solution is to install the latest packages. Many
customers find it easier to use the Caldera System Updater, called
cupdate (or kcupdate under the KDE environment), to update these
packages rather than downloading and installing them by hand.
