Debian DSA-3255-1 : zeromq3 - security update

medium Nessus Plugin ID 83335

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that libzmq, a lightweight messaging kernel, is susceptible to a protocol downgrade attack on sockets using the ZMTP v3 protocol. This could allow remote attackers to bypass ZMTP v3 security mechanisms by sending ZMTP v2 or earlier headers.

Solution

Upgrade the zeromq3 packages.

For the stable distribution (jessie), this problem has been fixed in version 4.0.5+dfsg-2+deb8u1.
