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

Notes

Author Note
mdeslaur this issue only affects the internal wpa ssl code. On Ubuntu, wpa is built with OpenSSL, so the affected files aren’t used at all
