Advisory number: 	CSSA-2003-007.0
Issue date: 		2003 February 17

1. Problem Description

	The Apache mod_dav module contains a format string vulnerability
	in the "ap_log_rerror()" function.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------

	OpenLinux 3.1.1 Server		prior to mod_dav-1.0.2_1.3.6-3.i386.rpm
					prior to mod_dav-devel-1.0.2_1.3.6-3.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to mod_dav-1.0.2_1.3.6-3.i386.rpm
					prior to mod_dav-devel-1.0.2_1.3.6-3.i386.rpm

	OpenLinux 3.1 Server		prior to mod_dav-1.0.2_1.3.6-3.i386.rpm
					prior to mod_dav-devel-1.0.2_1.3.6-3.i386.rpm

	OpenLinux 3.1 Workstation	prior to mod_dav-1.0.2_1.3.6-3.i386.rpm
					prior to mod_dav-devel-1.0.2_1.3.6-3.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.
