FRRouting/frr from v2.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the opaque_info_detail function at ospf_opaque.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted LS Update packet.

An update of the frr package has been released.

The remote Debian 12 / 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6322 advisory.

    Several vulnerabilities were discovered in FRRouting (frr), a suite of     internet routing protocol daemons. A remote attacker could trigger these     issues by sending specially crafted protocol packets to a vulnerable     daemon, resulting in denial of service (infinite loops, NULL pointer     dereferences and crashes) or potentially the execution of arbitrary code     through out-of-bounds reads and writes and buffer overflows. The flaws     affect packet and attribute parsing in the BGP daemon (including FlowSpec,     EVPN/VNC NLRI and MP_REACH_NLRI handling), the OSPF daemon (Traffic     Engineering, Segment Routing and Opaque LSA processing) and the babeld     daemon.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 8.4.4-1.1~deb12u2.

    For the stable distribution (trixie), these problems have been fixed in     version 10.3-3+deb13u1.

    We recommend that you upgrade your frr packages.
