Debian DLA-1352-1 : jruby security update

high Nessus Plugin ID 109091

Language:

Synopsis

The remote Debian host is missing a security update.

Description

An unsafe object deserialization vulnerability was found in jruby, a 100% pure-Java implementation of Ruby. An attacker can use this flaw to run arbitrary code when gem owner is run on a specially crafted YAML file.

For Debian 7 'Wheezy', these problems have been fixed in version 1.5.6-5+deb7u2.

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.
