Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple flaws exist in the Samba suite of programs, the most serious |
| 19 |
of which could result in the execution of arbitrary code. |
| 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 >= 3.0.24 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
A format string vulnerability exists in the VFS module when handling |
| 38 |
AFS file systems and an infinite loop has been discovered when handling |
| 39 |
file rename operations. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A user with permission to write to a shared AFS file system may be able |
| 45 |
to compromise the smbd process and execute arbitrary code with the |
| 46 |
permissions of the daemon. The infinite loop could be abused to consume |
| 47 |
excessive resources on the smbd host, denying service to legitimate |
| 48 |
users. |
| 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-3.0.24" |
| 62 |
|
