This could result in hostapd -process terminating in wpabuf length validation. Fix this by rejecting -messages that have invalid TLS Message Length value. - -This would affect cases that use the internal EAP authentication server -in hostapd either directly with IEEE 802.1X or when using hostapd as a -RADIUS authentication server and when receiving an incorrectly -constructed EAP-TLS message. Cases where hostapd uses an external -authentication are not affected. - -Thanks to Timo Warns for finding and reporting this issue. - -Signed-hostap: Jouni Malinen <j@w1.fi> -intended-for: hostap-1 -(cherry picked from commit 586c446e0ff42ae00315b014924ec669023bd8de) ---- - src/eap_server/eap_server_tls_common.c | 8 ++++++++ - 1 files changed, 8 insertions(+), 0 deletions(-) - -diff --git a/src/eap_server/eap_server_tls_common.c b/src/eap_server/eap_server_tls_common.c -index e149ee3..2cbe700 100644 ---- a/src/eap_server/eap_server_tls_common.c -+++ b/src/eap_server/eap_server_tls_common.c -@@ -224,6 +224,14 @@ static int eap_server_tls_process_fragment(struct eap_ssl_data *data, - return -1; - } - -+ if (len > message_length) { -+ wpa_printf(MSG_INFO, "SSL: Too much data (%d bytes) in " -+ "first fragment of frame (TLS Message " -+ "Length %d bytes)", -+ (int) len, (int) message_length); -+ return -1; -+ } -+ - data->tls_in = wpabuf_alloc(message_length); - if (data->tls_in == NULL) { - wpa_printf(MSG_DEBUG, "SSL: No memory for message"); --- -1.7.4-rc1 - |
