Juniper JSA10943

Medium Nessus Plugin ID 127122


The remote device is missing a vendor-supplied security patch.


The version of Junos OS installed on the remote host is prior to 16.1R7-S3, 16.2R2-S9, 17.1R3, 17.2R3, 17.2X75-D105, 17.3R3-S2, 17.4R1-S7, 18.1R3-S2, 18.2R2, 18.2X75-D12, or 18.3R1-S4. It is, therefore, affected by a denial of service (DoS) vulnerability which exists in Junos devices with the BGP graceful restart helper mode enabled or the BGP graceful restart mechanism enabled due to a certain sequence of BGP session restart on a remote peer that has the graceful restart mechanism enabled which may cause the local routing protocol daemon (RPD) process to crash and restart. An unauthenticated, local attacker can exploit this issue, via a certain sequence of BGP session restart, to cause a repeated crashes of the RPD process which can cause prolonged Denial of Service (DoS) as referenced in the JSA10943 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
