+	  <p>The otrl_base64_otr_decode() function and similar functions within OTR
+	  suffer from buffer overflows in the case of malformed input;
+	  specifically if a message of the format of "?OTR:===." is received
+	  then a zero-byte allocation is performed without a similar correlation
+	  between the subsequent base64 decoding write, as such it becomes
+	  possible to write between zero and three bytes incorrectly to the
+	  heap, albeit only with a value of '='.</p>
+	  <p>Because this code path is highly utilized, specifically in the
+	  reception of instant messages over pidgin or similar, this
+	  vulnerability is considered severe even though in many platforms and
+	  circumstances the bug would yield an unexploitable state and result
+	  simply in denial of service.</p>
+	  <p>The developers of OTR promptly fixed the errors and users of OTR are
+	  advised to upgrade the software at the next release cycle.</p>
