OS and Junos OS Evolved: If in a traffic engineering scenario a specific valid BGP-LS attribute is received rpd crashes","description":"An Incomplete List of Disallowed Inputs vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).\n\nWhen in a BGP traffic engineering scenario a specific, valid, optional, non-transitive BGP update is received over an established BGP session, RPD crashes and automatically restarts, which leads to traffic impact until routing has reconverged.\n\nThis issue affects:\nJunos OS:\n\n\n  *  All versions before 23.2R2-S6;\n  *  23.4 versions before 23.4R2-S7;\n  *  24.2 versions before 24.2R2-S4;\n  *  24.4 versions before
