Описание
An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial-Of-Service (DoS).
When an affected system receives a specific BGP EVPN update message over an established BGP session, this causes an rpd crash and restart.
A BGP EVPN configuration is not necessary to be vulnerable. If peers are not configured to send BGP EVPN updates to a vulnerable device, then this issue can't occur.
This issue affects iBGP and eBGP, over IPv4 and IPv6.
This issue affects: Junos OS:
- 23.4 versions from
23.4R2-S3 before 23.4R2-S5,
- 24.2 versions from
24.2R2
before 24.2R2-S1,
- 24.4 versions before 24.4R1-S3, 24.4R2;
Junos OS Evolved:
- 23.4-EVO versions from 23.4R2-S2-EVO before 23.4R2-S5-EVO,
- 24.2-EVO versions from 24.2R2-EVO before 24.2R2-S1-EVO,
- 24.4-EVO versions before 24.4R1-S3-EVO, 24.4R2-EVO.
