+	  <p>
+	    The vulnerability is caused by an insufficient check on
+	    the length of a decompressed domain name within a DNS
+	    packet.
+	  </p>
+	  <p>
+	    An attacker can craft a malicious DNS packet containing a
+	    highly compressed domain name. When the resolv library
+	    parses such a packet, the name decompression process
+	    consumes a large amount of CPU resources, as the library
+	    does not limit the resulting length of the name.
+	  </p>
+	  <p>
+	    This resource consumption can cause the application thread
+	    to become unresponsive, resulting in a Denial of Service
+	    condition.
