Ubuntu 12.04 LTS / 14.04 LTS / 15.10 : firefox vulnerability (USN-2893-1)

high Nessus Plugin ID 88711
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Jason Pang discovered that service workers intercept responses to plugin network requests made through the browser. An attacker could potentially exploit this to bypass same origin restrictions using the Flash plugin. (CVE-2016-1949).

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 firefox package.
