GLSA-200501-21 : HylaFAX: hfaxd unauthorized login vulnerability

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200501-21
(HylaFAX: hfaxd unauthorized login vulnerability)

The code used by hfaxd to match a given username and hostname with
an entry in the hosts.hfaxd file is insufficiently protected against
malicious entries.

Impact :

If the HylaFAX installation uses a weak hosts.hfaxd file, a remote
attacker could authenticate using a malicious username or hostname and
bypass the intended access restrictions.

Workaround :

As a workaround, administrators may consider adding passwords to
all entries in the hosts.hfaxd file.

http://www.gentoo.org/security/en/glsa/glsa-200501-21.xml

Solution :

All HylaFAX users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/hylafax-4.2.0-r2'
Note: Due to heightened security, weak entries in the
hosts.hfaxd file may no longer work. Please see the HylaFAX
documentation for details of accepted syntax in the hosts.hfaxd file.

Risk factor :

High / CVSS Base Score : 7.5
