Security Vulnerabilities in PBS Pro

PBS Professional security updates are primarily made available as minor version patches. We recommend using the latest minor version available, as it will likely also contain other non-security-related fixes. All known critical and high security issues are always fixed in the next major release, when it comes out.

List of Security Vulnerabilities

Vulnerabilities list the major releases that are affected and the versions where they were resolved. If the vulnerability was exploitable without a valid login, this is also stated. We also will classify the vulnerability, but we urge all users to read the description to determine if the bug affects specific installations or not.  The following table lists all known security issues and their status. Please note that this table starts at PBS Professional version 14.

(If the above table is empty, no vulnerabilities have been reported.)

This advisory to users running PBS Professional is to alert them to a security vulnerability. This is a privilege escalation vulnerability that potentially affects all users.  An attacker who successfully exploits this vulnerability could gain administrator privilege (root access) on PBS server (aka headnode) hosts. The attacker would need to be an authenticated user authorized to submit jobs on the cluster.
