Name of the Vulnerable Software and Affected Versions Junos OS versions prior to 21.2R3-S6 Junos OS versions 21.3 prior to 21.3R3-S5 Junos OS versions 21.4 prior to 21.4R3-S5 Junos OS versions 22.1 prior to 22.1R3-S3 Junos OS versions 22.2 prior to 22.2R3-S1 Junos OS versions 22.3 prior to 22.3R2-S2, 22.3R3 Junos OS versions 22.4 prior to 22.4R2-S1, 22.4R3
Description A Stack-based Buffer Overflow vulnerability in the Flow Processing Daemon (flowd) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). When URL filtering is enabled and a specific URL request is received and processed, flowd will crash and restart, leading to a sustained Denial of Service (DoS) condition if the specific URL request is continuously received.
Recommendations For Junos OS versions prior to 21.2R3-S6, update to version 21.2R3-S6 or later. For Junos OS versions 21.3 prior to 21.3R3-S5, update to version 21.3R3-S5 or later. For Junos OS versions 21.4 prior to 21.4R3-S5, update to version 21.4R3-S5 or later. For Junos OS versions 22.1 prior to 22.1R3-S3, update to version 22.1R3-S3 or later. For Junos OS versions 22.2 prior to 22.2R3-S1, update to version 22.2R3-S1 or later. For Junos OS versions 22.3 prior to 22.3R2-S2, 22.3R3, update to version 22.3R2-S2, 22.3R3 or later. For Junos OS versions 22.4 prior to 22.4R2-S1, 22.4R3, update to version 22.4R2-S1, 22.4R3 or later. As a temporary workaround, consider disabling URL filtering until a patch is available.
