Synopsis |
16 |
======== |
17 |
|
18 |
A large number of share connection requests could cause a Denial of |
19 |
Service within Samba. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Samba is a freely available SMB/CIFS implementation which allows |
25 |
seamless interoperability of file and print services to other SMB/CIFS |
26 |
clients. |
27 |
|
28 |
Affected packages |

Description |
37 |
=========== |
38 |
|
39 |
During an internal audit the Samba team discovered that a flaw in the |
40 |
way Samba stores share connection requests could lead to a Denial of |
41 |
Service. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
By sending a large amount of share connection requests to a vulnerable |
47 |
Samba server, an attacker could cause a Denial of Service due to memory |
48 |
consumption. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All Samba users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.22-r3" |
