SCO Security Advisory
Subject: OpenLinux: Integer overflow may allow local users to
cause a denial of service or possibly execute arbitrary code
Advisory number: CSSA-2004-006.0
Issue date: 2004 March 01
Cross reference: sr886799 fz528469 erg712481 CAN-2003-0854 CAN-2003-0853

1. Problem Description
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the following names to these issues:
CAN-2003-0854 ls in the fileutils or coreutils packages allows
local users to consume a large amount of memory via a large -w
value, which can be remotely exploited via applications that use
ls, such as wu-ftpd.
CAN-2003-0853 An integer overflow in ls in the fileutils or
coreutils packages may allow local users to cause a denial of
service or execute arbitrary code via a large -w value, which
could be remotely exploited via applications that use ls, such
as wu-ftpd.
2. Vulnerable Supported Versions
System Package
----------------------------------------------------------------------
OpenLinux 3.1.1 Server prior to fileutils-4.1-6.i386.rpm
OpenLinux 3.1.1 Workstation prior to fileutils-4.1-6.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.
