Debian DLA-2027-1 : jruby security update

high Nessus Plugin ID 131960

Language:

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.
