Vulnerability Title
Junos OS: QFX5000 Series: DMA memory leak is observed when specific DHCP packets are transmitted over pseudo-VTEP
Source: CVE Program / CVE List V5
Vulnerability Description
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;
* 21.2 versions prior to 21.2R3-S5;
* 21.3 versions prior to 21.3R3-S4;
* 21.4 versions prior to 21.4R3-S3;
* 22.1 versions prior to 22.1R3-S2;
* 22.2 versions prior to 22.2R2-S2, 22.2R3;
* 22.3 versions prior to 22.3R2-S1, 22.3R3;
* 22.4 versions prior to 22.4R1-S2, 22.4R2.
