Errata |
19 |
====== |
20 |
|
21 |
This advisory incorrectly described Samba versions as being vulnerable |
22 |
to a remote denial of service. After further verifications, it appears |
23 |
that a remote user can only deny service to himself, so this bug does |
24 |
not induce any security issue at all. The corrected sections appear |
25 |
below. |
26 |
|
27 |
Synopsis |
28 |
======== |
29 |
|
30 |
Samba has a bug with out of sequence print change notification |
31 |
requests, but it cannot be used to perform a remote denial of service |
32 |
attack. |
33 |
|
34 |
Affected packages |
35 |
================= |
36 |
|
37 |
There are no affected packages. |
38 |
|
39 |
Description |
40 |
=========== |
41 |
|
42 |
Due to a bug in the printer_notify_info() function, authorized users |
43 |
could potentially crash their smbd process by sending improperly |
44 |
handled print change notification requests in an invalid order. Windows |
45 |
XP SP2 clients can trigger this behavior by sending a |
46 |
FindNextPrintChangeNotify() request before previously sending a |
47 |
FindFirstPrintChangeNotify() request. |
48 |
|
49 |
Impact |
50 |
====== |
51 |
|
52 |
We incorrectly thought that this bug could be exploited to deny service |
53 |
to all Samba users. It is not the case, this bug has no security impact |
54 |
whatsoever. Many thanks to Jerry Carter from the Samba team for |
55 |
correcting our mistake. |
56 |
|
57 |
Workaround |
58 |
========== |
59 |
|
60 |
There is no need for a workaround. |
61 |
|
62 |
Resolution |
63 |
========== |
64 |
|
65 |
Samba users can keep their current versions. |
