An Improper Input Validation vulnerability in the Packet Forwarding Engine of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause memory leak, leading to Denial of Service (DoS).
On all Junos OS QFX5000 Series platforms, when pseudo-VTEP (Virtual Tunnel End Point) is configured under EVPN-VXLAN scenario, and specific DHCP packets are transmitted, DMA memory leak is observed. Continuous receipt of these specific DHCP packets will cause memory leak to reach 99% and then cause the protocols to stop working and traffic is impacted, leading to Denial of Service (DoS) condition. A manual reboot of the system recovers from the memory leak.
To confirm the memory leak, monitor for "sheaf:possible leak" and "vtep not found" messages in the logs.
This issue affects:
Juniper Networks Junos OS QFX5000 Series:
* All versions prior to 20.4R3-S6;
* 21.1 versions prior to 21.1R3-S5;
