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

Description |
37 |
=========== |
38 |
|
39 |
Multiple vulnerabilities have been discovered in MIT Kerberos 5. Please |
40 |
review the CVE identifiers referenced below for details. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
A remote attacker may be able to execute arbitrary code with the |
46 |
privileges of the administration daemon or the Key Distribution Center |
47 |
(KDC) daemon, cause a Denial of Service condition, or possibly obtain |
48 |
sensitive information. Furthermore, a remote attacker may be able to |
49 |
spoof Kerberos authorization, modify KDC responses, forge user data |
50 |
messages, forge tokens, forge signatures, impersonate a client, modify |
51 |
user-visible prompt text, or have other unspecified impact. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There is no known workaround at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All MIT Kerberos 5 users should upgrade to the latest version: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.9.2-r1" |
