+  <title>zgv, xzgv: Heap overflow</title>
+  <synopsis>
+    xzgv and zgv attempt to decode JPEG images within the CMYK/YCCK colour
+    space incorrectly, potentially resulting in the execution of arbitrary

+  <description>
+    <p>
+    Andrea Barisani of Gentoo Linux discovered xzgv and zgv allocate
+    insufficient memory when rendering images with more than 3 output
+    components, such as images using the YCCK or CMYK colour space. When
+    xzgv or zgv attempt to render the image, data from the image overruns a
+    heap allocated buffer.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    An attacker may be able to construct a malicious image that executes
+    arbitrary code with the permissions of the xzgv or zgv user when
+    attempting to render the image.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All xzgv users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=media-gfx/xzgv-0.8-r2"</code>
+    <p>
+    All zgv users should also upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=media-gfx/zgv-5.9"</code>
