FreeBSD : libzrtpcpp -- multiple security vulnerabilities (04320e7d-ea66-11e2-a96e-60a44c524f57)

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.
