Ubuntu Security Notice 6984-1 - It was discovered that WebOb incorrectly handled certain URLs. An attacker could possibly use this issue to control a redirect or forward to another URL.
### Impact When WebOb normalizes the HTTP Location header to include the request hostname, it does so by parsing the URL that the user is to be redirected to with Python's urlparse, and joining it to the base URL. `urlparse` however treats a `//` at the start of a string as a URI without a scheme, and then treats the next part as the hostname. `urljoin` will then use that hostname from the second part as the hostname replacing the original one from the request. ``` >>> parse.urlparse("//example.com/test/path") ParseResult(scheme='', netloc='example.com', path='/test/path', params='', query='', fragment='') ``` WebOb uses `urljoin` to take the request URI and joining the redirect location, so assuming the request URI is: `https://example.org//example.com/some/path`, and the URL to redirect to (for example by adding a slash automatically) is `//example.com/some/path/` that gets turned by `urljoin` into: ``` >>> parse.urljoin("https://example.org//attacker.com/some/path", "//attacker....
