title: Junos OS: rpd daemon cores due to malformed BGP UPDATE packet
description: Junos OS may be impacted by the receipt of a malformed BGP UPDATE which can lead to a routing process daemon (rpd) crash and restart. Receipt of a repeated malformed BGP UPDATEs can result in an extended denial of service condition for the device. This malformed BGP UPDATE does not propagate to other BGP peers.
