Subject:                OpenLinux: rsync heap based overflow
Advisory number:        CSSA-2004-010.0
Issue date:             2004 March 02
Cross reference:        sr888533 fz528609 erg712514 CAN-2003-0962
______________________________________________________________________________


1. Problem Description

        Heap-based buffer overflow in rsync before 2.5.7, when running in
        server mode, allows remote attackers to execute arbitrary code
        and possibly escape the chroot jail. 

        The Common Vulnerabilities and Exposures project (cve.mitre.org) 
        has assigned the name CAN-2003-0962 to this issue.


2. Vulnerable Supported Versions

        System                          Package
        ----------------------------------------------------------------------
        OpenLinux 3.1.1 Server          prior to rsync-2.5.7-1.i386.rpm
        OpenLinux 3.1.1 Workstation     prior to rsync-2.5.7-1.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.
