"The version of Junos OS installed on the remote host is affected by a DoS vulnerability as referenced in the JSA69915
advisory. An Improper Validation of Syntactic Correctness of Input vulnerability in the kernel of Juniper Networks
Junos OS Evolved on PTX series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS).

This issue only affects PTX10004, PTX10008, PTX10016. No other PTX Series devices or other platforms are affected.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
