An Improper Validation of Syntactic Correctness of Input vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause a 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 Juniper Networks
Junos OS:

20.4 versions 20.4R1 and later versions earlier than 20.4R3-S9;
21.2 versions earlier than 21.2R3-S7;
21.3 versions earlier than 21.3R3-S5;
21.4 versions earlier than 21.4R3-S5;
22.1 versions earlier than 22.1R3-S4;
22.2 versions earlier than 22.2R3-S3;
22.3 versions earlier than 22.3R3-S1;
22.4 versions earlier than 22.4R3;
23.2 versions earlier than 23.2R1-S2, 23.2R2;

Junos OS Evolved:

20.4-EVO versions 20.4R1-EVO and later versions earlier than 20.4R3-S9-EVO;
21.2-EVO versions earlier than 21.2R3-S7-EVO;
21.3-EVO versions earlier than 21.3R3-S5-EVO;
21.4-EVO versions earlier than 21.4R3-S5-EVO;
22.1-EVO versions earlier than 22.1R3-S4-EVO;
22.2-EVO versions earlier than 22.2R3-S3-EVO;
22.3-EVO versions earlier than 22.3R3-S1-EVO;
22.4-EVO versions earlier than 22.4R3-EVO;
23.2-EVO versions earlier than 23.2R1-S2-EVO, 23.2R2-EVO;

This issue does not affect Juniper Networks

Junos OS versions earlier than 20.4R1;
Junos OS Evolved versions earlier than 20.4R1-EVO.

This is a related but separate issue than the one described in JSA79095.
