<description>
|
|
<p>
|
|
A stack buffer overflow (CVE-2007-3999) has been reported in
|
|
svcauth_gss_validate() of the RPC library of kadmind. Another
|
|
vulnerability (CVE-2007-4000) has been found in
|
|
kadm5_modify_policy_internal(), which does not check the return values
|
|
of krb5_db_get_policy() correctly.
|
|
</p>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
The RPC related vulnerability can be exploited by a remote
|
|
unauthenticated attacker to execute arbitrary code with root privileges
|
|
on the host running kadmind. The second vulnerability requires the
|
|
remote attacker to be authenticated and to have "modify policy"
|
|
privileges. It could then also allow for the remote execution of
|
|
arbitrary code.

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

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

<code>

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