[vpnc-devel] dereference NULL

[Plamen Todorov]

Hello,

In vpnc.c file, function do_phase2_notice_check() the pointer *r_p is not checked for NULL. I had a situation when unpack_verify_phase2() returned ISAKMP_N_UNEQUAL_PAYLOAD_LENGTHS and left *r_p to be NULL which later lead to crash.

Probably do_phase2_notice_check() should return -1 in this situation to handle the error gracefully.
