Brief introduction

Multiple vulnerbilities were discovered in frr, the FRRouting suite of
internet protocols, while processing malformed requests and packets the BGP
daemon may have reachable assertions, NULL pointer dereference, out-of-bounds
memory access, which may lead to denial of service attack.

For the oldstable distribution (bullseye), these problems have been fixed
in version 7.5.1-1.1+deb11u2.

For the stable distribution (bookworm), these problems have been fixed in
version 8.4.4-1.1~deb12u1.

We recommend that you upgrade your frr packages.
