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.
