The detail of the memory leak follows:
File name: ospf_interface.c
Function name: ospf_if_new_hook().
Type of leak: Overwriting the already allocated memory.
Problem found and description:
The ospf_new_if_params() fn allocates a memory for "auth_crypt" which
is overwritten, down in the fn (ospf_if_new_hook) by explicitely allocating
a memory for the same "auth_crypt".
