CVE-2019-13132 is a critical memory corruption vulnerability in Canonical Ubuntu Linux, published on 10 Jul 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
In ZeroMQ libzmq before 4.0.9, 4.1.x before 4.1.7, and 4.2.x before 4.3.2, 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.
