Debian DLA-254-1 : librack-ruby security update

medium Nessus Plugin ID 84408

Language:

Synopsis

The remote Debian host is missing a security update.

Description

There is a potential denial of service vulnerability in Rack, a modular Ruby webserver interface.

Carefully crafted requests can cause a `SystemStackError` and cause a denial of service attack by exploiting the lack of a sensible depth check when doing parameter normalization.

We recommend that you update your librack-ruby 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 packages.
