    Package : bind9
    CVE ID : CVE-2020-8625
    Debian Bug : 983004

    A buffer overflow vulnerability was discovered in the SPNEGO
    implementation affecting the GSSAPI security policy negotiation in BIND,
    a DNS server implementation, which could result in denial of service
    (daemon crash), or potentially the execution of arbitrary code.

    For the stable distribution (buster), this problem has been fixed in
    version 1:9.11.5.P4+dfsg-5.1+deb10u3.

    We recommend that you upgrade your bind9 packages.

    For the detailed security status of bind9 please refer to its security
    tracker page at:
    https://security-tracker.debian.org/tracker/bind9
