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 vulnerability in the SIP ALG packet processing service which allows an attacker to cause a Denial of Service (DoS) to the device. A remote, unauthenticated attacker can exploit this by sending specific types of valid SIP traffic to the device to cause the flowd process to crash and generate a core dump while processing SIP ALG traffic. Continued receipt of these SIP packets will cause the device to stop responding.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionApply the relevant Junos software release referenced in Juniper advisory JSA10953.
