Description GLSAMaker/CVETool Bot gentoo-dev 2019-05-13 15:30:40 UTC
CVE-2019-11555 (https://nvd.nist.gov/vuln/detail/CVE-2019-11555):
  The EAP-pwd implementation in hostapd (EAP server) before 2.8 and
  wpa_supplicant (EAP peer) before 2.8 does not validate fragmentation
  reassembly state properly for a case where an unexpected fragment could be
  received. This could result in process termination due to a NULL pointer
  dereference (denial of service). This affects eap_server/eap_server_pwd.c
  and eap_peer/eap_pwd.c.

Nevermind, this still needs to be stabilized.
