    Debian Bug     :

    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.

    For the detailed security status of frr please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/frr
