CVSS: 7.5EPSS: 0%CPEs: 22EXPL: 1CVE-2021-31353 – Junos OS and Junos OS Evolved: RPD core upon receipt of specific BGP update
https://notcve.org/view.php?id=CVE-2021-31353
19 Oct 2021 — An Improper Handling of Exceptional Conditions vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows an attacker to inject a specific BGP update, causing the routing protocol daemon (RPD) to crash and restart, leading to a Denial of Service (DoS). Continued receipt and processing of the BGP update will create a sustained Denial of Service (DoS) condition. This issue affects very specific versions of Juniper Networks Junos OS: 19.3R3-S2; 19.4R3-S3; 20.2 versions 20.2R2-S3 and later, prior to... • https://kb.juniper.net/JSA11218 • CWE-755: Improper Handling of Exceptional Conditions •
