FRRouting/frr from v2.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the ospf_opaque_lsa_dump function at ospf_opaque.c. This vulnerability allows attackers to cause a Denial of Service (DoS) under specific malformed LSA conditions.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
