# CVE-2024-30395

> 8.7 HIGH

## Beschreibung

An Improper Validation of Specified Type of Input vulnerability in Routing Protocol Daemon (RPD) of Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause Denial of Service (DoS).

If a BGP update is received over an established BGP session which contains a tunnel encapsulation attribute with a specifically malformed TLV, rpd will crash and restart.

  *  all versions before 21.2R3-S7, 

  *  from 21.3 before 21.3R3-S5, 

  *  from 21.4 before 21.4R3-S5, 

  *  from 22.1 before 22.1R3-S5, 

  *  from 22.2 before 22.2R3-S3, 

  *  from 22.3 before 22.3R3-S2, 

  *  from 22.4 before 22.4R3, 

  *  from 23.2 before 23.2R1-S2, 23.2R2.





Junos OS Evolved:



  *  all versions before 21.2R3-S7-EVO, 

  *  from 21.3-EVO before 21.3R3-S5-EVO, 

  *  from 21.4-EVO before 21.4R3-S5-EVO, 
  *  from 22.2-EVO before 22.2R3-S3-EVO,
