CVE-2020-1684

On Juniper Networks SRX Series configured with application identification inspection enabled, receipt of specific HTTP t

On Juniper Networks SRX Series configured with application identification inspection enabled, receipt of specific HTTP traffic can cause high CPU load utilization, which could lead to traffic interruption.
