SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionThe version of Junos OS installed on the remote host is prior to 16.1R7-S6, 16.2R2-S11, 17.1R2-S11, 17.2R1-S9, 17.2X75-D105, 17.3R2-S5, 17.4R2-S8, 18.1R3-S8, 18.2R2-S6, 18.2X75-D12, 18.3R1-S6, 18.4R1-S5, 19.1R1-S3, or 19.2R1-S2.
It is, therefore, affected by a denial of service (DoS) vulnerability. An unauthenticated, remote attacker can exploit this, by sending a specific BGP UPDATE message, in order to cause other peers to terminate the established BGP session as referenced in the JSA11013 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
