OVERVIEW |
15 |
|
16 |
File descriptors introduced in 2.3.4 can be used to crash xinetd |
17 |
resulting in a denial of service. |
18 |
|
19 |
DETAIL |
20 |
|
21 |
Solar Designer found a vulnerability in xinetd, a replacement for the |
22 |
BSD derived inetd. File descriptors for the signal pipe introduced in |
23 |
version 2.3.4 are leaked into services started from xinetd. The |
24 |
descriptors could be used to talk to xinetd resulting in crashing it |
25 |
entirely. This is usually called a denial of service. |
26 |
|
27 |
SOLUTION |
28 |
|
29 |
It is recommended that all Gentoo Linux users who are running |
30 |
sys-apps/xinetd-2.3.5 and earlier update their systems as follows. |
31 |
|
32 |
emerge rsync |
33 |
emerge xinetd |
34 |
emerge clean |
35 |
|
36 |
xinetd-2.3.7 is currently only available for x86. Sparc and ppc will |
37 |
be available when it's been tested on these archs. |
