CVE-2020-26569

https://notcve.org/view.php?id=CVE-2020-26569

In EVPN VxLAN setups in Arista EOS, specific malformed packets can lead to incorrect MAC to IP bindings and as a result packets can be incorrectly forwarded across VLAN boundaries. This can result in traffic being discarded on the receiving VLAN. This affects versions: 4.21.12M and below releases in the 4.21.x train; 4.22.7M and below releases in the 4.22.x train; 4.23.5M and below releases in the 4.23.x train; 4.24.2F and below releases in the 4.24.x train. En unas configuraciones EVPN VxLAN en Arista EOS, los paquetes malformados específicos pueden conllevar a enlaces incorrectos de MAC a IP y, como resultado, los paquetes pueden ser reenviados incorrectamente a través de los límites de la VLAN. Esto puede causar que el tráfico se descarte en la VLAN receptora. • https://www.arista.com/en/support/advisories-notices/security-advisories/11997-security-advisory-57 •
