From a4e73a0e470cde6fcf3983aca277f01540bb37fa Mon Sep 17 00:00:00 2001 From: Alexander Couzens Date: Sun, 1 Apr 2012 13:36:52 +0300 Subject: [PATCH] Fix potential double free and use of freed memory in RADIUS client ieee802_1x_encapsulate_radius() frees the RADIUS message if radius_client_send() returns error. This could have resulted in use of freed memory and double freeing of the RADIUS message if send() fails since the message is also left in the retransmit list. Avoid this by not returning error to the caller in such a case.
