MIT Kerberos 5 is a suite of applications that implement the Kerberos |
| 40 |
network protocol. kadmind is the MIT Kerberos 5 administration daemon. |

| 45 |
A stack buffer overflow (CVE-2007-3999) has been reported in |
| 46 |
svcauth_gss_validate() of the RPC library of kadmind. Another |
| 47 |
vulnerability (CVE-2007-4000) has been found in |
| 48 |
kadm5_modify_policy_internal(), which does not check the return values |
| 49 |
of krb5_db_get_policy() correctly. |
| 50 |
</p> |
| 51 |

| 52 |
<impact type="high"> |
| 53 |
<p> |
| 54 |
The RPC related vulnerability can be exploited by a remote |
| 55 |
unauthenticated attacker to execute arbitrary code with root privileges |
| 56 |
on the host running kadmind. The second vulnerability requires the |
| 57 |
remote attacker to be authenticated and to have "modify policy" |
| 58 |
privileges. It could then also allow for the remote execution of |
| 59 |
arbitrary code. |
| 60 |

<workaround> |
| 63 |
<p> |
| 64 |
There is no known workaround at this time. |

</workaround> |

<resolution> |
| 68 |
<p> |
| 69 |
All MIT Kerberos 5 users should upgrade to the latest version: |

# emerge --sync |
| 73 |
# emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.5.3-r1"</code> |
