+	  <p>Vulnerability 1. Remote Heap Overflow: If an attacker sends a packet larger than 1024 bytes that gets stored temporarily (which occurs many times - such as when sending a ZRTP Hello packet), a heap overflow will occur, leading to potential arbitrary code execution on the vulnerable host.</p>
+	  <p>Vulnerability 2. Multiple Stack Overflows: ZRTPCPP contains multiple stack overflows that arise when preparing a response to a client's ZRTP Hello packet.</p>
+	  <p>Vulnerability 3. Information Leaking / Out of Bounds Reads: The ZRTPCPP library performs very little validation regarding the expected size of a packet versus the actual amount of data received. This can lead to both information leaking and out of bounds data reads (usually resulting in a crash). Information leaking can be performed for example by sending a malformed ZRTP Ping packet.</p>
