An Improperly Implemented Security Check for Standard vulnerability in storm control of Juniper Networks Junos OS QFX5k devices allows packets to be punted to ARP queue causing a l2 loop resulting in a DDOS violations and DDOS syslog.
This issue is triggered when Storm control is enabled and ICMPv6 packets are present on device.
This issue affects Juniper Networks:
Junos OS
- All versions prior to 20.2R3-S6 on QFX5k;
- 20.3 versions prior to 20.3R3-S5 on QFX5k;
- 20.4 versions prior to 20.4R3-S5 on QFX5k;
- 21.1 versions prior to 21.1R3-S4 on QFX5k;
- 21.2 versions prior to 21.2R3-S3 on QFX5k;
- 21.3 versions prior to 21.3R3-S2 on QFX5k;
- 21.4 versions prior to 21.4R3 on QFX5k;
- 22.1 versions prior to 22.1R3 on QFX5k;
- 22.2 versions prior to 22.2R2 on QFX5k.
