This script is Copyright (C) 2007-2016 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200701-14
(Mod_auth_kerb: Denial of Service)

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.

Impact :

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.

Workaround :

There is no known workaround at this time.

Solution :

All mod_auth_kerb users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=www-apache/mod_auth_kerb-5.0_rc7-r1'

Risk factor :

Medium / CVSS Base Score : 5.0
CVSS Temporal Score : 5.0
