Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Samba contains multiple vulnerabilities potentially resulting in the |
| 19 |
execution of arbitrary code with root privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Samba is a suite of SMB and CIFS client/server programs for UNIX. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 net-fs/samba < 3.0.24-r2 >= 3.0.24-r2 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Samba contains a logical error in the smbd daemon when translating |
| 38 |
local SID to user names (CVE-2007-2444). Furthermore, Samba contains |
| 39 |
several bugs when parsing NDR encoded RPC parameters (CVE-2007-2446). |
| 40 |
Lastly, Samba fails to properly sanitize remote procedure input |
| 41 |
provided via Microsoft Remote Procedure Calls (CVE-2007-2447). |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker could exploit these vulnerabilities to gain root |
| 47 |
privileges via various vectors. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All Samba users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.24-r2" |
| 61 |
|
