|
Mod_auth_kerb is an Apache authentication module using Kerberos.

|
<p>
|
|
Mod_auth_kerb improperly handles component byte encoding in the
|
|
der_get_oid() function, allowing for a buffer overflow to occur if
|
|
there are no components which require more than one byte for encoding.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could try to access a Kerberos protected resource on an
|
|
Apache server with an incorrectly configured service principal and
|
|
crash the server process. It is important to note that this buffer
|
|
overflow is not known to allow for the execution of code.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All mod_auth_kerb users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-apache/mod_auth_kerb-5.0_rc7-r1"</code>
|
|
</resolution>
