Package : wpa
Version : 2:2.7+git20190128+0c1e29f-6+deb10u4
CVE ID : CVE-2023-52160
Debian Bug : 1064061

It was discovered that there was a potential authentication bypass
vulnerability in wpa, a set of tools including the widely-used
wpasupplicant client for authenticating with WPA and WPA2 wireless
networks.

For an attack to have been successful, wpasupplicant must have been
configured to not verify the network's TLS certificate during Phase 1
of the authentication cycle; a eap_peap_decrypt vulnerability could
have been used to skip Phase 2 authentication by sending an EAP-TLV
"Success" packet instead of starting Phase 2.

For Debian 10 buster, this problem has been fixed in version
2:2.7+git20190128+0c1e29f-6+deb10u4.

We recommend that you upgrade your wpa packages.
