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.

Ein entfernter Angreifer kann mehrere Schwachstellen in Juniper JUNOS, Juniper MX Series, Juniper SRX Series und Juniper Security Director ausnutzen, um Daten zu manipulieren oder offenzulegen, Sicherheitsmaßnahmen zu umgehen, Code auszuführen, einen Denial of Service zu verursachen oder seine Privilegien zu erweitern.
