Detail
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.
