A Stack-based Buffer Overflow vulnerability in Flow Processing Daemon (flowd) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS).

On all Junos OS MX Series platforms with SPC3 and MS-MPC/-MIC, when URL filtering is enabled and a specific URL request is received and processed, flowd will crash and restart. Continuous reception of the specific URL request will lead to a sustained Denial of Service (DoS) condition.

This issue affects:
Junos OS:

  • all versions before 21.2R3-S6,

  • from 21.3 before 21.3R3-S5,

  • from 21.4 before 21.4R3-S5,

  • from 22.1 before 22.1R3-S3,

  • from 22.2 before 22.2R3-S1,

  • from 22.3 before 22.3R2-S2, 22.3R3,

  • from 22.4 before 22.4R2-S1, 22.4R3.
