This issue affects Junos OS: * 22.1 releases 22.1R1 and later before 22.2R3-S5, * 22.3 releases before 22.3R3-S4, * 22.4 releases before 22.4R3-S4, * 23.2 releases before 23.2R2-S2, * 23.4 releases before 23.4R2-S1, * 24.2 releases before 24.2R1-S1, 24.2R2. Please note that the PR does indicate that earlier versions have been fixed as well, but these won't be adversely impacted by this.
