Arista CloudEOS

On affected platforms running Arista EOS, an authorized attacker with permissions to perform gNMI requests could craft a request allowing it to update arbitrary configurations in the switch.

A vulnerability exists in Arista’s Cloud EOS VM / vEOS 4.23.2M and below releases in the 4.23.x train, 4.22.4M and below releases in the 4.22.x train, 4.21.3M to 4.21.9M releases in the 4.21.x train, 4.21.3FX-7368.*, 4.21.4-FCRFX.*, 4.21.4.1, 4.21.7.1, 4.22.2.0.1, 4.22.2.2.1, 4.22.3.1, and 4.23.2.1 Router code in a scenario where TCP MSS options are configured.

On affected platforms running Arista EOS with SNMP configured, a specially crafted packet can cause a memory leak in the snmpd process.

On affected platforms running Arista CloudEOS an issue in the Software Forwarding Engine (Sfe) can lead to a potential denial of service attack by sending malformed packets to the switch.

On affected platforms running Arista CloudEOS a size check bypass issue in the Software Forwarding Engine (Sfe) may allow buffer over reads in later code. Additionally, depending on configured options this may cause a recomputation of the TCP checksum ...

On the affected platforms running EOS, a malformed DHCP packet might cause the DHCP relay agent to restart.
