Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been found in MIT Kerberos 5 |
| 19 |
Applications, the most severe of which may allow execution of arbitrary |
| 20 |
code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
A suite of applications that implement the Kerberos 5 network protocol |
| 26 |
from MIT. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Multiple vulnerabilities have been discovered in MIT Kerberos 5 |
| 40 |
Applications: |
| 41 |
|
| 42 |
* An error in the FTP daemon prevents it from dropping its initial |
| 43 |
effective group identifier (CVE-2011-1526). |
| 44 |
* A boundary error in the telnet daemon and client could cause a buffer |
| 45 |
overflow (CVE-2011-4862). |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
An unauthenticated remote attacker may be able to execute arbitrary |
| 51 |
code with the privileges of the user running the telnet daemon or |
| 52 |
client. Furthermore, an authenticated remote attacker may be able to |
| 53 |
read or write files owned by the same group as the effective group of |
| 54 |
the FTP daemon. |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There is no known workaround at this time. |
| 60 |
|
| 61 |
Resolution |
| 62 |
========== |
| 63 |
|
| 64 |
All MIT Kerberos 5 Applications users should upgrade to the latest |
| 65 |
version: |
| 66 |
|
| 67 |
# emerge --sync |
| 68 |
# emerge --ask --oneshot -v ">=app-crypt/mit-krb5-appl-1.0.2-r1" |
| 69 |
