15 |
Roberto Zunino discovered a vulnerability in the MIT-SHM extension of |
16 |
XFree86 prior to versions 4.2.1. The vulnerability allows a local |
17 |
user who can run XFree86 to gain read/write access to any shared |
18 |
memory segment in the system. Although the use of shared memory |
19 |
segments to store trusted data is not a common practice, by |
20 |
exploiting this vulnerability the attacker potentially can get and/or |
21 |
change sensitive information. |
22 |
|
23 |
SOLUTION |
24 |
|
25 |
It is recommended that all Gentoo Linux users who are running |
26 |
x11-base/xfree-4.2.0-r12 and earlier update their systems |
27 |
as follows: |
28 |
|
29 |
emerge rsync |
30 |
emerge xfree |
31 |
emerge clean |
