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).
When 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.
This issue affects:
Junos OS:
* All versions before 23.2R2-S6;
* 23.4 versions before 23.4R2-S7;
* 24.2 versions before 24.2R2-S4;
* 24.4 versions before 24.4R2-S4;
* 25.2 versions before 25.2R1-S2, 25.2R2;
Junos OS Evolved:
* All versions before 23.2R2-S6-EVO;
* 23.4 versions before 23.4R2-S8.11-EVO;
* 24.2 versions before 24.2R2-S4-EVO;
* 24.4 versions before 24.4R2-S5-EVO;
* 25.2 versions before 25.2R1-S2-EVO, 25.2R2-EVO;
