GSD-2023-22393

Vulnerability from gsd - Updated: 2023-12-13 01:20

Details

An Improper Check for Unusual or Exceptional Conditions vulnerability in BGP route processing of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to cause Routing Protocol Daemon (RPD) crash by sending a BGP route with invalid next-hop resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects systems without import policy configured. This issue affects: Juniper Networks Junos OS 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3-S3; 21.3 versions prior to 21.3R3-S2; 21.4 versions prior to 21.4R2-S2, 21.4R3; 22.1 versions prior to 22.1R1-S2, 22.1R2; 22.2 versions prior to 22.2R1-S1, 22.2R2. Juniper Networks Junos OS Evolved 21.4-EVO versions prior to 21.4R2-S2-EVO, 21.4R3-EVO; 22.1-EVO versions prior to 22.1R1-S2-EVO, 22.1R2-EVO; 22.2-EVO versions prior to 22.2R1-S1-EVO, 22.2R2-EVO. This issue does not affect: Juniper Networks Junos OS versions prior to 21.1R1. Juniper Networks Junos OS Evolved versions prior to 21.3R1-EVO.
