+  <background>
+    <p>libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX,
+      SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and
+      decompression.
+    </p>
+  </background>
+  <description>
+    <p>The accelerated Huffman decoder was previously invoked if there were 128
+      bytes in the input buffer. However, it is possible to construct a JPEG
+      image with Huffman blocks &gt; 430 bytes in length. This release simply
+      increases the minimum buffer size for the accelerated Huffman decoder to
+      512 bytes, which should accommodate any possible input.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>A remote attacker could coerce the victim to run a specially crafted
+      image file resulting in the execution of arbitrary code.

+  <workaround>
+    <p>There is no known workaround at this time.</p>
