Debian DLA-215-1 : libjson-ruby security update

high Nessus Plugin ID 83167


The remote Debian host is missing a security update.


The JSON gem for Ruby allowed remote attackers to cause a denial of service (resource consumption) or bypass the mass assignment protection mechanism via a crafted JSON document that triggers the creation of arbitrary Ruby symbols or certain internal objects, as demonstrated by conducting a SQL injection attack against Ruby on Rails, aka 'Unsafe Object Creation Vulnerability.'

For Debian 6 'Squeeze', this issue has been fixed in libjson-ruby version 1.1.9-1+deb6u1.

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.


Upgrade the affected packages.
