A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 14.04 LTS


Swift did not properly perform input validation of certain HTTP headers.

Software Description

John Dickinson discovered that Swift did not properly quote the WWW-Authenticate header value. If a user were tricked into navigating to a malicious Swift URL, an attacker could conduct cross-site scripting attacks. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data, within the same domain.
