    Debian Bug     : 934180 940080
    
    Two vulnerabilities were found in the WPA protocol implementation found in
    wpa_supplication (station) and hostapd (access point).
    
    CVE-2019-13377
    
        A timing-based side-channel attack against WPA3's Dragonfly handshake when
        using Brainpool curves could be used by an attacker to retrieve the
        password.
    
    CVE-2019-16275
    
        Insufficient source address validation for some received Management frames
        in hostapd could lead to a denial of service for stations associated to an
        access point. An attacker in radio range of the access point could inject a
        specially constructed unauthenticated IEEE 802.11 frame to the access point
        to cause associated stations to be disconnected and require a reconnection
        to the network.
    
    For the oldstable distribution (stretch), these problems have been fixed
    in version $stretch_VERSION.
    
    For the stable distribution (buster), these problems have been fixed in
    version 2:2.7+git20190128+0c1e29f-6+deb10u1.
    
    We recommend that you upgrade your wpa packages.
