Synopsis |
19 |
======== |
20 |
|
21 |
Samba is vulnerable to a remote denial of service attack due to out of |
22 |
sequence print change notification requests. |
23 |
|
24 |
Background |
25 |
========== |
26 |
|
27 |
Samba is a freely available SMB/CIFS implementation which allows |
28 |
seamless interoperability of file and print services to other SMB/CIFS |
29 |
clients. |
30 |
|
31 |
Affected packages |
32 |
================= |
33 |
|

------------------------------------------------------------------- |

Package / Vulnerable / Unaffected |

1 net-fs/samba < 3.0.6 >= 3.0.6 |

Description |
40 |
=========== |
41 |
|
42 |
Due to a bug in the printer_notify_info() function, authorized users |
43 |
could potentially crash the Samba server by sending improperly handled |
44 |
print change notification requests in an invalid order. Windows XP SP2 |
45 |
clients can trigger this behavior by sending a |
46 |
FindNextPrintChangeNotify() request before previously sending a |
47 |
FindFirstPrintChangeNotify() request. |
48 |
|
49 |
Impact |
50 |
====== |
51 |
|
52 |
A remote authorized user could potentially crash a Samba server after |
53 |
issuing these out of sequence requests. |
54 |
|
55 |
Workaround |
56 |
========== |
57 |
|
58 |
There is no known workaround at this time. |
59 |
|
60 |
Resolution |
61 |
========== |
62 |
|
63 |
All Samba users should upgrade to the latest version: |
64 |
|
65 |
# emerge sync |
66 |
|
67 |
# emerge -pv ">=net-fs/samba-3.0.6" |
68 |
# emerge ">=net-fs/samba-3.0.6" |
69 |
