Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been discovered in MIT Kerberos 5, |
| 19 |
allowing execution of arbitrary code or Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
MIT Kerberos 5 is a suite of applications that implement the Kerberos |
| 25 |
network protocol. |
| 26 |
|
| 27 |
Affected packages |
| 28 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Multiple vulnerabilities have been discovered in the Key Distribution |
| 39 |
Center in MIT Kerberos 5. Please review the CVE identifiers referenced |
| 40 |
below for details. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could send a specially crafted request, possibly |
| 46 |
resulting in execution of arbitrary code with the privileges of the |
| 47 |
process or a Denial of Service condition. Additionally, a remote |
| 48 |
attacker could impersonate a kadmind server and send a specially |
| 49 |
crafted packet to the password change port, which can result in a |
| 50 |
ping-pong condition and a Denial of Service condition. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All MIT Kerberos 5 users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.11.4" |
| 64 |
