The EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP peer) doesn't properly validate fragmentation reassembly state when receiving an unexpected fragment. This could lead to a process crash due to a NULL pointer derefrence. An attacker in radio range of a station or access point with EAP-pwd support could cause a crash of the relevant process (wpa_supplicant or hostapd), ensuring a denial of service. For the stable distribution (stretch), this problem has been fixed in version 2:2.4-1+deb9u4. 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 Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@...ts.debian.org -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEE8vi34Qgfo83x35gF3rYcyPpXRFsFAlzn/TEACgkQ3rYcyPpX RFspSAf/YMVZvCbELRqK4sZ42zqtP5UCpTx2usFHGakULukrdYOv4Jh9uHjME/VX WAzY9sNIBGIlTpCW/P3qnIbwQaZLcVlZ9fF4JrepuArBC+Cr8Q3sYmUVoiPUTvTv Sm9nj0M3A9yDukRSw8gPWPSjk8z1r4J2LMnCwyxNxug3Iqphr7CMdhTvOzowaEk6 hP18tVx4MHhemzag5zKCo7pLCuVxWyJYL9ndEpFuSl1si7EDUIeWkX9gWeLouIAN zfExE2zUwfgdAzPdH3k4JvYABn7azTp1NgMSlzTTtT9r4yUkg80ilHi5mpeV0oLj 5G4VKNeNRoBOPjNOmOIa1tq6C2rS7g== =hAb9 -----END PGP SIGNATURE-----
