-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ 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. 4.
