 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4123-1 [email protected] https://www.debian.org/lts/security/ Bastien Roucaris April 12, 2025 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : wpa Version : 2:2.9.0-21+deb11u3 CVE ID : CVE-2022-23303 CVE-2022-23304 CVE-2022-37660

 Multiple vulnerabilities were found in wpa, a set of tools including the widely-used wpasupplicant client for authenticating with WPA and WPA2 wireless networks.

 CVE-2022-23303

 The implementations of SAE in hostapd are vulnerable to side channel attacks as a result of cache access patterns.

 CVE-2022-23304

 The implementations of EAP-pwd are vulnerable to side-channel attacks as a result of cache access patterns.

 CVE-2022-37660

 The PKEX code remains active even after a successful PKEX association. An attacker that successfully bootstrapped public keys with another entity using PKEX in the past, will be able to subvert a future bootstrapping by passively observing public keys.

 For Debian 11 bullseye, these problems have been fixed in version 2:2.9.0-21+deb11u3.

 We recommend that you upgrade your wpa packages.

 For the detailed security status of wpa please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/wpa
