critical Nessus Plugin ID 149977

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Fang-Pen Lin reports :

A remote, unauthenticated client connecting to a libzmq application, running with a socket listening with CURVE encryption/authentication enabled, may cause a stack overflow and overwrite the stack with arbitrary data, due to a buffer overflow in the library. Users running public servers with the above configuration are highly encouraged to upgrade as soon as possible, as there are no known mitigations.

Solution

Update the affected package.
