+ <h1>Problem Description:</h1>
+ <p>Side channel attacks in the SAE implementations used by both
+ hostapd (AP) and wpa_supplicant (infrastructure BSS station/mesh
+ station). SAE (Simultaneous Authentication of Equals) is also known
+ as WPA3-Personal. The discovered side channel attacks may be able to
+ leak information about the used password based on observable timing
+ differences and cache access patterns. This might result in full
+ password recovery when combined with an offline dictionary attack and
+ if the password is not strong enough to protect against dictionary
+ attacks.</p>
+ <p>See
+ https://w1.fi/security/2019-1/sae-side-channel-attacks.txt
+ for a detailed description of the bug.</p>
+ <h1>Impact:</h1>
+ <p>All wpa_supplicant and hostapd versions with SAE support
+ (CONFIG_SAE=y in the build configuration and SAE being enabled in
+ the runtime configuration).</p>
