+ Mod_auth_kerb is vulnerable to a buffer overflow possibly allowing a Denial
+ of Service.

+ <package name="www-apache/mod_auth_kerb" auto="yes" arch="*">

+ <background>
+ <p>
+ Mod_auth_kerb is an Apache authentication module using Kerberos.
+ </p>
+ </background>
+ <description>
+ <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 "&gt;=www-apache/mod_auth_kerb-5.0_rc7-r1"</code>
