Name of the Vulnerable Software and Affected Versions Juniper Networks Junos OS versions prior to 19.3R3-S7 Juniper Networks Junos OS 19.4 versions prior to 19.4R2-S8, 19.4R3-S10 Juniper Networks Junos OS 20.2 versions prior to 20.2R3-S6 Juniper Networks Junos OS 20.3 versions prior to 20.3R3-S5 Juniper Networks Junos OS 20.4 versions prior to 20.4R3-S5 Juniper Networks Junos OS 21.1 versions prior to 21.1R3-S4 Juniper Networks Junos OS 21.2 versions prior to 21.2R3 Juniper Networks Junos OS 21.3 versions prior to 21.3R3 Juniper Networks Junos OS 21.4 versions prior to 21.4R2
Description The issue is related to a Missing Release of Memory after Effective Lifetime vulnerability in the Flow Processing Daemon (flowd) of Juniper Networks Junos OS. This vulnerability allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). In an IPsec VPN environment, a memory leak will be seen if a DH or ECDH group is configured. Eventually, the flowd process will crash and restart.
