Description
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.
