+  <title>Xpdf, GPdf: Stack overflow in Decrypt::makeFileKey2</title>
+  <synopsis>
+    A stack overflow was discovered in Xpdf, potentially resulting in the
+    execution of arbitrary code. GPdf includes Xpdf code and therefore is
+    vulnerable to the same issue.

+    <p>
+    iDEFENSE reports that the Decrypt::makeFileKey2 function in Xpdf's
+    Decrypt.cc insufficiently checks boundaries when processing /Encrypt

+  <impact type="normal">
+    <p>
+    An attacker could entice an user to open a specially-crafted PDF
+    file which would trigger a stack overflow, potentially resulting in
+    execution of arbitrary code with the rights of the user running Xpdf or
+    GPdf.

+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Xpdf users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=app-text/xpdf-3.00-r8&quot;</code>

+    All GPdf users should also upgrade to the latest version:

+    <code>
+    # emerge --sync
