    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.

    - CVE-2026-37458: missing input validation in the `MP_REACH_NLRI` component allows authenticated attackers     to cause a       DoS via a crafted UPDATE message (bsc#1263974).

The remote Fedora 44 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2026-28949d21e5 advisory.

    New version of frr and grout. I am keeping libyang to version 3 at the moment due to recommendations from     https://github.com/FRRouting/frr/blob/master/doc/developer/building-libyang.rst. Once changes to build     with libyang5 land, I will rebase libyang as well.
