Juniper Junos SRX Series Network Security Daemon DoS (JSA10692)
Medium Nessus Plugin ID 84768
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionAccording to its self-reported version number, the remote Juniper Junos device is affected by a denial of service vulnerability in the network security daemon (nsd) due to a flaw that occurs when handling DNS response messages for name resolution requests. An attacker can exploit this, via a rogue DNS server designed to respond to the SRX device with specially crafted DNS packets, to crash the nsd process, resulting in a denial of service condition.
