Subject: Linux: integer overflow vulnerability in XDR/RPC routines
Advisory number: CSSA-2003-013.0
Issue date: 2003 March 19
Cross reference:

1. Problem Description
The xdrmem_getbytes() function in the XDR library provided by
Sun Microsystems contains an integer overflow that can lead to
improperly sized dynamic memory allocation.
2. Vulnerable Supported Versions
System Package

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.
