+	  <p>The four libcurl functions curl_escape(), curl_easy_escape(),
+	    curl_unescape and curl_easy_unescape perform string URL percent
+	    escaping and unescaping. They accept custom string length inputs
+	    in signed integer arguments.</p>
+	  <p>The provided string length arguments were not properly checked
+	    and due to arithmetic in the functions, passing in the length
+	    0xffffffff (2^32-1 or UINT_MAX or even just -1) would end up
+	    causing an allocation of zero bytes of heap memory that curl
+	    would attempt to write gigabytes of data into.</p>
