SUSE-SA:2002:032: xf86

medium Nessus Plugin ID 13754

Synopsis

The remote host is missing a vendor-supplied security patch

Description

The remote host is missing the patch for the advisory SUSE-SA:2002:032 (xf86).


The xf86 package contains various libraries and programs which are fundamental for the X server to function.
The libX11.so library from this package dynamically loads other libraries where the pathname is controlled by the user invoking the program linked against libX11.so. Unfortunately, libX11.so also behaves the same way when linked against setuid programs. This behavior allows local users to execute arbitrary code under a different UID which can be the root-UID in the worst case.
libX11.so has been fixed to check for calls from setuid programs. It denies loading of user controlled libraries in this case.
We recommend an update in any case since there is no easy workaround possible except removing the setuid bit from any program linked against libX11.so.

Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command 'rpm -Fhv file.rpm' to apply the update.
