"The version of Junos OS installed on the remote host is affected by a vulnerability as referenced in the JSA11261
advisory.
- An Insufficient Algorithmic Complexity combined with an Allocation of Resources Without Limits or
Throttling vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series
and MX Series with SPC3 allows an unauthenticated network attacker to cause latency in transit packet
processing and even packet loss. If transit traffic includes a significant percentage (> 5%) of fragmented
packets which need to be reassembled, high latency or packet drops might be observed. This issue affects
Juniper Networks Junos OS on SRX Series, MX Series with SPC3: All versions prior to 18.2R3; 18.3 versions
prior to 18.3R3; 18.4 versions prior to 18.4R2-S9, 18.4R3; 19.1 versions prior to 19.1R2; 19.2 versions
prior to 19.2R1-S1, 19.2R2. (CVE-2022-22153)
