SCO Security Advisory
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.
