CVE-2024-30395
Junos OS and Junos OS Evolved: A malformed BGP tunnel encapsulation attribute will lead to an rpd crash
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. This issue affects:
