    Package        : libu2f-host
    CVE ID         : CVE-2018-20340
    Debian Bug     : 921725
    
    Christian Reitter discovered that libu2f-host, a library implementing
    the host-side of the U2F protocol, failed to properly check for a
    buffer overflow. This would allow an attacker with a custom made
    malicious USB device masquerading as a security key, and physical
    access to a computer where PAM U2F or an application with libu2f-host
    integrated, to potentially execute arbitrary code on that computer.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 1.1.2-2+deb9u1.
    
    We recommend that you upgrade your libu2f-host packages.
    
    For the detailed security status of libu2f-host please refer to
    its security tracker page at:
