Debian LTS Advisory DLA-2443-1 debian-lts@lists.debian.org
https://www.debian.org/lts/security/ Utkarsh Gupta

Package : zeromq3
Version : 4.2.1-4+deb9u3
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 Debian 9 stretch, this problem has been fixed in version
4.2.1-4+deb9u3.
We recommend that you upgrade your zeromq3 packages.
For the detailed security status of zeromq3 please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/zeromq3
