Debian DLA-2027-1 : jruby security update

high Nessus Plugin ID 131960

Language:

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 Debian host is missing a security update.

Description

Several security vulnerabilities were found in Ruby that also affected Debian's JRuby package, a pure-Java implementation of Ruby. Attackers were able to call arbitrary Ruby methods, cause a denial of service or inject input into HTTP response headers when using the WEBrick module.

For Debian 8 'Jessie', these problems have been fixed in version 1.5.6-9+deb8u2.

We recommend that you upgrade your jruby packages.

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

Solution

Upgrade the affected jruby package.
