*** Pendiente de traducción *** 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.<br /> <br /> <br /> <br /> This issue affects Junos OS on MX Series with SPC3 and SRX Series:<br /> <br /> <br /> * all versions before 23.2R2-S7,<br /> * 23.4 versions before 23.4R2-S8,<br /> * 24.2 versions before 24.2R2-S5,<br /> * 24.4 versions before 24.4R2-S4,<br /> * 25.2 versions before 25.2R2,<br /> * 25.4 versions before 25.4R1-S2.
