Debian: DLA-1867-1 Critical: wpa Authentication Issues Overview

CVE-2019-9495

Cache-based side-channel attack against the EAP-pwd implementation:
an attacker able to run unprivileged code on the target machine
(including for example javascript code in a browser on a smartphone)
during the handshake could deduce enough information to discover the
password in a dictionary attack.

This issue has only very partially been mitigated against by reducing
measurable timing differences during private key operations. More
work is required to fully mitigate this vulnerability.

CVE-2019-9497

Reflection attack against EAP-pwd server implementation: a lack of
validation of received scalar and elements value in the
EAP-pwd-Commit messages could have resulted in attacks that would
have been able to complete EAP-pwd authentication exchange without
the attacker having to know the password. This did not result in the
attacker being able to derive the session key, complete the following
key exchange and access the network.
