+  <title>HylaFAX: hfaxd unauthorized login vulnerability</title>
+  <synopsis>
+    HylaFAX is subject to a vulnerability in its username matching code,
+    potentially allowing remote users to bypass access control lists.
+  </synopsis>
+  <product type="ebuild">HylaFAX</product>
+  <announced>January 11, 2005</announced>

+  <affected>
+    <package name="net-misc/hylafax" auto="yes" arch="*">
+      <unaffected range="ge">4.2.0-r2</unaffected>
+      <vulnerable range="lt">4.2.0-r2</vulnerable>

+  <background>
+    <p>
+    HylaFAX is a software package for sending and receiving facsimile
+    messages.
+    </p>
+  </background>
+  <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 &quot;&gt;=net-misc/hylafax-4.2.0-r2&quot;</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.
+    </p>
+  </resolution>
