New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.6

Synopsis

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

Description

According to its self-reported version number, the remote Juniper Junos device is affected by a vulnerability in the path computational element protocol daemon (pccd) process. An unauthenticated, remote attacker can exploit this issue, by sending malformed Path Computation Element Protocol (PCEP) packets to a Junos OS device serving as a Path Computation Client (PCC) in a PCEP environment in order to cause the pccd process to crash and generate a core file, thereby causing a Denial of Service (DoS) condition.

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

Solution

Apply the relevant Junos software release referenced in Juniper advisory JSA10980.
