    - ------------------------------------------------------------------------- Debian Security Advisory DSA-4761-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso September 07, 2020 https://www.debian.org/security/faq

    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 (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 at:
    https://security-tracker.debian.org/tracker/zeromq3
