Synopsis
The remote FreeBSD host is missing a security-related update.Description
Mark Dowd reports :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.
Vulnerability 2. Multiple Stack Overflows: ZRTPCPP contains multiple stack overflows that arise when preparing a response to a client's ZRTP Hello packet.
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.
