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 allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). If a sequence of specific PIM packets is received, this will cause a flowd crash and restart. This issue affects Junos OS: * all versions before 21.2R3-S9, * 21.4 versions before 21.4R3-S11, * 22.2 versions before 22.2R3-S7, * 22.4 versions before 22.4R3-S6, * 23.2 versions before 23.2R2-S4, * 23.4 versions before 23.4R2-S4, * 24.2 versions before 24.2R2. This is a similar, but different vulnerability than the issue reported as CVE-2024-47503, published in JSA88133.
