Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities in MIT Kerberos 5 could potentially result in |
| 19 |
the execution of arbitrary code. |
| 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 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 app-crypt/mit-krb5 < 1.5.2 >= 1.5.2 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
The Kerberos administration daemon, and possibly other applications |
| 39 |
using the GSS-API or RPC libraries, could potentially call a function |
| 40 |
pointer in a freed heap buffer, or attempt to free an uninitialized |
| 41 |
pointer. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker may be able to crash an affected application, or |
| 47 |
potentially execute arbitrary code with root privileges. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All MIT Kerberos 5 users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.5.2" |
| 61 |
