Debian: CVE-2018-16471: ruby-rack -- security update

Severity CVSS Published Added Modified
4 (AV:N/AC:M/Au:N/C:N/I:P/A:N) November 13, 2018 February 19, 2019 February 19, 2019

Description

There is a possible XSS vulnerability in Rack before 2.0.6 and 1.6.11. Carefully crafted requests can impact the data returned by the `scheme` method on `Rack::Request`. Applications that expect the scheme to be limited to 'http' or 'https' and do not escape the return value could be vulnerable to an XSS attack. Note that applications using the normal escaping mechanisms provided by Rails may not impacted, but applications that bypass the escaping mechanisms, or do not use them may be vulnerable.
