Summary
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:
* All versions 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:
* All versions before 21.4R3-S9-EVO,
* from 22.2 before 22.2R3-S5-EVO,
* from 22.3 before 22.3R3-S4-EVO,
* from 22.4 before 22.4R3-S5-EVO,
* from 23.2 before 23.2R2-S3-EVO,
* from 23.4 before 23.4R2-S2-EVO,
* from 24.2 before 24.2R1-S2-EVO, 24.2R2-EVO.
This is a similar, but different vulnerability than the issue reported as CVE-2024-39516.
