SCO Security Advisory

Subject: OpenLinux: slocate local user buffer overflow
Advisory number: CSSA-2004-001.0
Issue date: 2004 February 10
Cross reference: sr886033 fz528414 erg712456
________________________________________________________________________

1. Problem Description

Heap-based buffer overflow in main.c of slocate 2.6, and possibly
other versions, may allow local users to gain privileges via a
modified slocate database that causes a negative "pathlen" value
to be used. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0848 to this issue.

2. Vulnerable Supported Versions

System Package
----------------------------------------------------------------------
OpenLinux 3.1.1 Server prior to slocate-2.7-1.i386.rpm
OpenLinux 3.1.1 Workstation prior to slocate-2.7-1.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.
