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: Junos OS: 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, from 22.3-EVO before 22.3R3-S2-EVO, from 22.4-EVO before 22.4R3-EVO, * from 23.2-EVO before 23.2R1-S2-EVO, 23.2R2-EVO. This is a related but separate issue than the one described in JSA75739.
