Details
An Expected Behavior Violation vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker sending a valid BGP UPDATE packet to cause a BGP session reset, 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:
- All versions before 21.2R3-S9,
- from 21.4 before 21.4R3-S11,
- from 22.2 before 22.2R3-S7,
- from 22.4 before 22.4R3-S7,
- from 23.2 before 23.2R2-S4,
- from 23.4 before 23.4R2-S4,
- from 24.2 before 24.2R2,
- from 24.4 before 24.4R1-S3, 24.4R2
Junos OS Evolved:
- All versions before 22.2R3-S7-EVO,
- from 22.4-EVO before 22.4R3-S7-EVO,
- from 23.2-EVO before 23.2R2-S4-EVO,
- from 23.4-EVO before 23.4R2-S4-EVO,
- from 24.2-EVO before 24.2R2-EVO,
- from 24.4-EVO before 24.4R1-S3-EVO, 24.4R2-EVO.
