상세 설명

An Improper Validation of Syntactic Correctness of Input vulnerability in the SIP plugin of Juniper Networks Junos OS on MX Series with SPC3 and SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).If the SIP ALG is enabled on an affected device, the processing of a malformed SIP invite packet will cause a flow processing daemon (flowd) crash and restart. This leads to a complete service outage until the system has automatically recovered.

This issue affects Junos OS on MX Series with SPC3 and SRX Series:

all versions before 23.2R2-S7,
23.4 versions before 23.4R2-S8,
24.2 versions before 24.2R2-S5,
24.4 versions before 24.4R2-S4,
25.2 versions before 25.2R2,
25.4 versions before 25.4R1-S2.
