Summary
Junos OS is prone to a kernel crash vulnerability.
Insight
Insight
Receipt of a specifically crafted UDP packet destined to an interface IP address of a Junos OS device with a 64-bit architecture may result in a kernel crash. This issue only affects systems with a 64-bit architecture. 32-bit systems are unaffected by this vulnerability. Only packets able to reach the RE through existing edge and control plane firewall filters, destined to the device itself, can trigger this issue. Junos OS is not vulnerable to transit UDP traffic.
