Junos OS and Junos OS Evolved: With certain BGP options enabled, receipt of specifically malformed BGP update causes RPD crash
CWE ID: CWE-125
Base Score (CVSS): N/A
CVE: CVE-2025-21600
Descrizione: An out-of-bounds read vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, logically adjacent BGP peer sending a specifically malformed BGP packet to cause rpd to crash and restart, 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 configured in either of two ways: * Systems with BGP traceoptions enabled * Systems with BGP family traffic-engineering (BGP-LS) configured and can be exploited from a directly connected and configured BGP peer. This issue affects iBGP and eBGP with any address family configured, 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; Junos OS Evolved: * From 21.4-EVO before 21.4R3-S9-EVO, * From 22.2-EVO before 22.2R3-S5-EVO, * From 22.3-EVO before 22.3R3-S4-EVO, * From 22.4-EVO before 22.4R3-S5-EVO, * From 23.2-EVO before 23.2R2-S3-EVO, * From 23.4-EVO before 23.4R2-S2-EVO, * From 24.2-EVO before 24.2R1-S2-EVO, 24.2R2-EVO. This issue does not affect versions of Junos OS prior to 21.3R1. This issue does not affect versions of Junos OS Evolved prior to 21.3R1-EVO. This is a similar, but different vulnerability than the issue reported as CVE-2024-39516.
