-Subject: [PATCH] radius: Prevent buffer overflow in rc_mksid()
-
-On some systems getpid() can return a value greater than 65535.
-Increase the size of buf[] to allow for this, and use slprintf()
-to make sure we never overflow it.

-Subject: [PATCH] pppd: Fix bounds check in EAP code
-
-Given that we have just checked vallen < len, it can never be the case
-that vallen >= len + sizeof(rhostname). This fixes the check so we
-actually avoid overflowing the rhostname array.

-Subject: [PATCH] pppd: Ignore received EAP messages when not doing EAP
-
-This adds some basic checks to the subroutines of eap_input to check
-that we have requested or agreed to doing EAP authentication before
-doing any processing on the received packet. The motivation is to
-make it harder for a malicious peer to disrupt the operation of pppd
-by sending unsolicited EAP packets. Note that eap_success() already
-has a check that the EAP client state is reasonable, and does nothing
-(apart from possibly printing a debug message) if not.
