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. This causes a leak of packet buffers and if enough malformed packets are received, the switch may eventually stop forwarding traffic. • https://www.arista.com/en/support/advisories-notices/security-advisory/17240-security-advisory-0085 • CWE-125: Out-of-bounds Read CWE-126: Buffer Over-read •

For certain systems running EOS, a Precision Time Protocol (PTP) packet of a management/signaling message with an invalid Type-Length-Value (TLV) causes the PTP agent to restart. Repeated restarts of the service will make the service unavailable. • https://www.arista.com/en/support/advisories-notices/security-advisory/15439-security-advisory-0076 • CWE-400: Uncontrolled Resource Consumption CWE-1284: Improper Validation of Specified Quantity in Input •

This advisory documents the impact of an internally found vulnerability in Arista EOS for security ACL bypass. The impact of this vulnerability is that the security ACL drop rule might be bypassed if a NAT ACL rule filter with permit action matches the packet flow. This could allow a host with an IP address in a range that matches the range allowed by a NAT ACL and a range denied by a Security ACL to be forwarded incorrectly as it should have been denied by the Security ACL. This can enable an ACL bypass. Este aviso documenta el impacto de una vulnerabilidad encontrada internamente en Arista EOS para omitir las ACL de seguridad. • https://www.arista.com/en/support/advisories-notices/security-advisory/15862-security-advisory-0078 • CWE-284: Improper Access Control •
