Fang-Pen Lin discovered a stack-based buffer-overflow flaw in ZeroMQ, a lightweight messaging kernel library. 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 or the execution of arbitrary code.

For the oldstable distribution (stretch), this problem has been fixed in version 4.2.1-4+deb9u2.

For the stable distribution (buster), this problem has been fixed in version 4.3.1-4+deb10u1.

We recommend that you upgrade your zeromq3 packages.
