Ubuntu 12.04 LTS / 14.04 LTS / 14.10 : maas regression (USN-2431-2)
High Nessus Plugin ID 79740
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-2431-1 fixed vulnerabilities in mod_wsgi. The security update exposed an issue in the MAAS package, causing a regression. This update fixes the problem.
We apologize for the inconvenience.
It was discovered that mod_wsgi incorrectly handled errors when setting up the working directory and group access rights. A malicious application could possibly use this issue to cause a local privilege escalation when using daemon mode.
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.
SolutionUpdate the affected maas-region-controller and / or maas-region-controller-min packages.
