[BPF] Fwd: [FROG] New Releases of FRR

[Humberto Galiza]

FYI. Sugiro a quem utiliza o VyOS com o FRR ao invés do Quagga
verificar se já há uma atualização do VyOS disponível com esse patch.

[]s!

All -

On Monday a research group installed into the global BGP routing table
a prefix with a attribute type of 0xFF, which is designated as
experimental by BGP RFC's.  FRR had a developmental escape that read
this attribute incorrectly and caused the bgp peering session to flap.
If you have compiled FRR with the `--enable-bgp-vnc` option and run
BGP as a peer on the global routing table you are vulnerable to this
issue.  This issue has been fixed in FRR with this commit:

https://github.com/FRRouting/frr/commit/943d595a018e69b550db08cccba1d0778a86705a

We have applied this fix to the stable/3.0(3.0.4), stable/4.0(4.0.1),
stable/5.0(5.0.2) and stable/6.0(6.0.2) branches.  New releases can be
found here:

https://github.com/FRRouting/frr/releases/tag/frr-3.0.4
https://github.com/FRRouting/frr/releases/tag/frr-4.0.1
https://github.com/FRRouting/frr/releases/tag/frr-5.0.2
https://github.com/FRRouting/frr/releases/tag/frr-6.0.2

Snap packaging and the FreeBSD ports have been updated as well.  We
recommend you update your installation of FRR immediately.

At this point we are applying for a CVE and will announce that
information when we have it.

In the near future we plan to implement RFC-7606 to handle this
situation better in BGP, if you have any questions please feel free to
email me, or to open up discussions on the frog alias.

thanks!
