Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
Some applications shipped with MIT Kerberos 5 are vulnerable to local |
| 20 |
privilege escalation. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
MIT Kerberos 5 is a suite of applications that implement the Kerberos |
| 26 |
network protocol. It is designed to provide strong authentication for |
| 27 |
client/server applications by using secret-key cryptography. |
| 28 |
|
| 29 |
Affected packages |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
Unchecked calls to setuid() in krshd and v4rcp, as well as unchecked |
| 41 |
calls to seteuid() in kftpd and in ksu, have been found in the MIT |
| 42 |
Kerberos 5 program suite and may lead to a local root privilege |
| 43 |
escalation. |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
A local attacker could exploit this vulnerability to execute arbitrary |
| 49 |
code with elevated privileges. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All MIT Kerberos 5 users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.4.3-r3" |
