Ubuntu 14.04 LTS / 16.04 LTS / 16.10 / 17.04 : juju-core vulnerability (USN-3300-1)

Critical Nessus Plugin ID 100509


The remote Ubuntu host is missing one or more security-related patches.


Ryan Beisner discovered juju did not set permissions on a Unix domain socket. A local attacker could use this flaw to gain administrative privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
