"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 Debian 8 'Jessie', this problem has been fixed in version
4.0.5+dfsg-2+deb8u2.

We recommend that you upgrade your zeromq3 packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
