    CVE-2024-30388

    An Improper Isolation or Compartmentalization vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on QFX5000 Series and EX Series allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). If a specific malformed LACP packet is received by a QFX5000 Series, or an EX4400, EX4100 or EX4650 Series device, an LACP flap will occur resulting in traffic loss. This issue affects Junos OS on QFX5000 Series, and on EX4400, EX4100 or EX4650 Series: * 20.4 versions from 20.4R3-S4 before 20.4R3-S8, * 21.2 versions from 21.2R3-S2 before 21.2R3-S6, * 21.4 versions from 21.4R2 before 21.4R3-S4, * 22.1 versions from 22.1R2 before 22.1R3-S3, * 22.2 versions before 22.2R3-S1, * 22.3 versions before 22.3R2-S2, 22.3R3, * 22.4 versions before 22.4R2-S1, 22.4R3.
