Description
A Reachable Assertion 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).<br />
<br />
When the device receives a specific BGP UPDATE packet, the rpd crashes and restarts. Continuous receipt of this specific packet will cause a sustained DoS condition.<br />
<br />
For the issue to occur, BGP multipath with "pause-computation-during-churn" must be configured on the device, and the attacker must send the paths via a BGP UPDATE from a established BGP peer.<br />
<br />
This issue affects:<br />
Junos OS: <br />
* All versions before 21.4R3-S7, <br />
* from 22.3 before 22.3R3-S3, <br />
* from 22.4 before 22.4R3-S5, <br />
* from 23.2 before 23.2R2, <br />
* from 23.4 before 23.4R2.<br />
<br />
<br />
<br />
Junos OS Evolved: <br />
* All versions before 21.4R3-S7-EVO, <br />
* from 22.3 before 22.3R3-S3-EVO, <br />
* from 22.4 before 22.4R3-S5-EVO, <br />
* from 23.2 before 23.2R2-EVO, <br />
* from 23.4 before 23.4R2-EVO.
