Description
A Buffer Over-read 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 an affected device receives a BGP update with a set of specific optional transitive attributes over an established peering session, rpd will crash and restart when attempting to advertise the received information to another peer.<br />
This issue can only happen if one or both of the BGP peers of the receiving session are non-4-byte-AS capable as determined from the advertised capabilities during BGP session establishment. Junos OS and Junos OS Evolved default behavior is 4-byte-AS capable unless this has been specifically disabled by configuring:<br />
<br />
[ protocols bgp ... disable-4byte-as ]<br />
<br />
<br />
Established BGP sessions can be checked by executing:<br />
<br />
show bgp neighbor | match "4 byte AS"<br />
<br />
<br />
