    Package        : bluez
    CVE ID         : CVE-2020-0556
    Debian Bug     : 953770
    
    It was reported that the BlueZ's HID and HOGP profile implementations
    don't specifically require bonding between the device and the host.
    Malicious devices can take advantage of this flaw to connect to a target
    host and impersonate an existing HID device without security or to cause
    an SDP or GATT service discovery to take place which would allow HID
    reports to be injected to the input subsystem from a non-bonded source.
    
    For the HID profile an new configuration option (ClassicBondedOnly) is
    introduced to make sure that input connections only come from bonded
    device connections. The options defaults to 'false' to maximize device
    compatibility.
    
    For the oldstable distribution (stretch), this problem has been fixed
    in version 5.43-2+deb9u2.
    
    For the stable distribution (buster), this problem has been fixed in
    version 5.50-1.2~deb10u1.
    
    We recommend that you upgrade your bluez packages.
