Ubuntu 17.04 : freeradius vulnerability (USN-3316-1)

critical Nessus Plugin ID 100678

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Stefan Winter and Lubos Pavlicek discovered that FreeRADIUS incorrectly handled the TLS session cache. A remote attacker could possibly use this issue to bypass authentication by resuming an unauthenticated session.

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.

Solution

Update the affected freeradius package.
