DESCRIPTION:
Two vulnerabilities have been reported in Ruby on Rails, which can be
exploited by malicious people to bypass certain security restrictions
and compromise a vulnerable system.

1) An error within the "attr_protected" method in ActiveRecord does
not properly restrict access to the blacklist of model attributes,
which can be exploited to modify certain otherwise restricted values
via a specially crafted request.

Successful exploitation of this vulnerability requires an application
using the "attr_protected" method.

This vulnerability is reported in versions prior to 3.2.12, 3.1.11,
and 2.3.17.

2) An input validation error within the "+serialize+" helper in
ActiveRecord when parsing serialized fields can be exploited to
deserialize arbitrary YAML input.

Successful exploitation of this vulnerability may allow execution of
arbitrary code but requires an application to allow input to be
assigned to the serialized fields.

This vulnerability is reported in versions 2.3.x and prior and 3.0.x
and prior.

SOLUTION:
Update to versions 3.2.12, 3.1.11, or 2.3.17.

PROVIDED AND/OR DISCOVERED BY:
