+    xine-lib contains multiple overflows potentially allowing execution of
+    arbitrary code.

+  <background>
+    <p>
+    xine-lib is a multimedia library which can be utilized to create
+    multimedia frontends.

+    <p>
+    Ariel Berkman discovered that xine-lib reads specific input data
+    into an array without checking the input size in demux_aiff.c, making
+    it vulnerable to a buffer overflow (CAN-2004-1300) . iDefense
+    discovered that the PNA_TAG handling code in pnm_get_chunk() does not
+    check if the input size is larger than the buffer size (CAN-2004-1187).
+    iDefense also discovered that in this same function, a negative value
+    could be given to an unsigned variable that specifies the read length
+    of input data (CAN-2004-1188).
+    </p>

+  <impact type="normal">
+    <p>
+    A remote attacker could craft a malicious movie or convince a
+    targeted user to connect to a malicious PNM server, which could result
+    in the execution of arbitrary code with the rights of the user running
+    any xine-lib frontend.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All xine-lib users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose media-libs/xine-lib</code>
