Ubuntu 12.04 LTS / 14.04 LTS / 14.10 : mod-wsgi vulnerability (USN-2431-1)

Medium Nessus Plugin ID 79717


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


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.


Update the affected libapache2-mod-wsgi and / or libapache2-mod-wsgi-py3 packages.
