Debian DSA-2604-1 : rails - insufficient input validation

high Nessus Plugin ID 63457

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that Rails, the Ruby web application development framework, performed insufficient validation on input parameters, allowing unintended type conversions. An attacker may use this to bypass authentication systems, inject arbitrary SQL, inject and execute arbitrary code, or perform a DoS attack on the application.

Solution

Upgrade the rails packages.

For the stable distribution (squeeze), this problem has been fixed in version 2.3.5-1.2+squeeze4.1.
