GENTOO LINUX SECURITY ANNOUNCEMENT 200210-006
- - --------------------------------------------------------------------

PACKAGE : xfree
SUMMARY : Shared memory may be compromised by local XFree86 users
DATE    : 2002-10-24 10:00 UTC
EXPLOIT : local

- - --------------------------------------------------------------------

Roberto Zunino discovered a vulnerability in the MIT-SHM extension of
XFree86 prior to versions 4.2.1. The vulnerability allows a local
user who can run XFree86 to gain read/write access to any shared
memory segment in the system. Although the use of shared memory
segments to store trusted data is not a common practice, by
exploiting this vulnerability the attacker potentially can get and/or
change sensitive information.

SOLUTION

It is recommended that all Gentoo Linux users who are running
x11-base/xfree-4.2.0-r12 and earlier update their systems
as follows:

emerge rsync
emerge xfree
emerge clean
