HylaFAX is a software package for sending and receiving facsimile
|
|
messages.

<description>
|
|
<p>
|
|
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.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
As a workaround, administrators may consider adding passwords to
|
|
all entries in the hosts.hfaxd file.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All HylaFAX users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/hylafax-4.2.0-r2"</code>
|
|
<p>
|
|
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.
|
|
