+  <title>libspf2: DNS response buffer overflow</title>
+  <synopsis>
+    A memory management error in libspf2 might allow for remote execution of
+    arbitrary code.

+  <background>
+    <p>
+    libspf2 is a library that implements the Sender Policy Framework,
+    allowing mail transfer agents to make sure that an email is authorized
+    by the domain name that it is coming from. Currently, only the exim MTA
+    uses libspf2 in Gentoo.
+    </p>
+  </background>
+  <description>
+    <p>
+    libspf2 uses a fixed-length buffer to receive DNS responses and does
+    not properly check the length of TXT records, leading to buffer
+    overflows.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A remote attacker could store a specially crafted DNS entry and entice
+    a user or automated system using libspf2 to lookup that SPF entry (e.g.
+    by sending an email to the MTA), possibly allowing for the execution of
+    arbitrary code.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All libspf2 users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=mail-filter/libspf2-1.2.8"</code>
