How to fix?

There is no fixed version for Echo:latest libsoup2.4.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup2.4 package and not the libsoup2.4 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

A flaw was found in libsoup. When libsoup clients encounter an HTTP redirect, they mistakenly send the HTTP Authorization header to the new host that the redirection points to. This allows the new host to impersonate the user to the original host that issued the redirect.
