Package : wpa
CVE ID : CVE-2019-13377 CVE-2019-16275
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.
