Summary
An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker sending a specific BGP update packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS).
Continuous receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.
This issue affects iBGP and eBGP, and both IPv4 and IPv6 are affected by this vulnerability.
This issue affects Junos OS:
* from 21.4 before 21.4R3-S9,
* from 22.2 before 22.2R3-S5,
* from 22.3 before 22.3R3-S4,
* from 22.4 before 22.4R3-S5,
* from 23.2 before 23.2R2-S3,
* from 23.4 before 23.4R2-S3,
* from 24.2 before 24.2R1-S2, 24.2R2;
This issue does not affect versions prior to 21.1R1.
Junos OS Evolved:
* from 21.4 before 21.4R3-S9-EVO,
* from 22.2 before 22.2R3-S5-EVO,
* from 22.3 before 22.3R3-S4-EVO,
* from 22.4 before 22.4R3-S5-EVO,
* from 23.2 before 23.2R2-S3-EVO,
* from 23.4 before 23.4R2-S3-EVO,
* from 24.2 before 24.2R1-S2-EVO, 24.2R2-EVO.
This issue does not affect versions prior to 21.1R1-EVO
