NVD Description

Note: Versions mentioned in the description apply only to the upstream hostapd package and not the hostapd package as distributed by Alpine. See How to fix? for Alpine:3.18 relevant fixed versions and status.

In wpa_supplicant and hostapd 2.9, forging attacks may occur because AlgorithmIdentifier parameters are mishandled in tls/pkcs1.c and tls/x509v3.c.
