An Out-of-Bounds Read vulnerability in
the routing protocol daemon (rpd) of
Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker 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 traffic engineering
configured
This issue can affect iBGP and eBGP with
any address family
configured. The specific attribute involved is non-transitive, and will not propagate across a network.
This issue affects:
Junos OS:
* All versions before 21.4R3-S8,
* 22.2 before 22.2R3-S5,
* 22.3 before 22.3R3-S4,
* 22.4 before 22.4R3-S3,
* 23.2 before 23.2R2-S2,
* 23.4 before 23.4R2;
Junos OS Evolved:
* All versions before 21.4R3-S8-EVO,
* 22.2-EVO before 22.2R3-S5-EVO,
* 22.3-EVO before 22.3R3-S4-EVO,
* 22.4-EVO before 22.4R3-S3-EVO,
* 23.2-EVO before 23.2R2-S2-EVO,
* 23.4-EVO before 23.4R2-EVO.
