Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
The cache manager of OpenAFS contains several bugs resulting in remote |
| 19 |
execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
OpenAFS is a distributed file system. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 net-fs/openafs < 1.4.9 >= 1.4.9 |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Two vulnerabilites were discovered: |
| 38 |
|
| 39 |
* Simon Wilkinson discovered from a bug report by Toby Blake that the |
| 40 |
cache manager of OpenAFS contains a heap-based buffer overflow which |
| 41 |
is related to the use of the ERR_PTR macro (CVE-2009-1250). |
| 42 |
|
| 43 |
* A pointer dereference bug when using XDR arrays was discovered by |
| 44 |
Simon Wilkinson, with assistance from Derrick Brashear and Jeffrey |
| 45 |
Altman. (CVE-2009-1251). |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
The vulnerabilites might allow remote unauthenticated attackers to |
| 51 |
cause a Denial of Service (system crash) and possibly execute arbitrary |
| 52 |
code. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround at this time. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All OpenAFS users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=net-fs/openafs-1.4.9" |
| 66 |
