Frrouting: >> Frrouting >> 3.0.4 Security Vulnerabilities
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.

In FRRouting (FRR) through 9.1, it is possible for the get_edge() function in ospf_te.c in the OSPF daemon to return a NULL pointer. In cases where calling functions do not handle the returned NULL value, the OSPF daemon crashes, leading to denial of service.
