An Improper Check for Unusual or Exceptional Conditions vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on

SRX1600, SRX2300, SRX 4000 Series, and SRX5000 Series with SPC3

  • 21.4 versions before 21.4R3-S11,
  • 22.2 versions before 22.2R3-S7,

  • 23.2 versions before 23.2R2-S4,
  • 23.4 versions before 23.4R2-S4,
