Ubuntu 14.04 LTS USN-2256-1 Critical: Swift Input Validation Issue

Scroller Ubuntu
Swift for Linux may be vulnerable due to flawed input sanitization, resulting in Cross-Site Scripting (XSS) vulnerabilities. Apply updates to address potential security risks.
Swift did not properly perform input validation of certain HTTP headers.

Summary

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

Software Description:

- swift: OpenStack distributed virtual object store

Details:

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.
