Debian security advisory DSA-4761-1 zeromq3.

Package: zeromq3
CVE ID: CVE-2020-15166

It was discovered that ZeroMQ, a lightweight messaging kernel library does not properly handle connecting peers before a handshake is completed.

A remote, unauthenticated client connecting to an application using the libzmq library, running with a socket listening with CURVE encryption/authentication enabled can take advantage of this flaw to cause a denial of service affecting authenticated and encrypted clients.

For the stable distribution Debian 10 "Buster", this problem has been fixed in version 4.3.1-4+deb10u2.

We recommend that you upgrade your zeromq3 packages.

For the detailed security status of zeromq3 please refer to its security tracker page.
