Debian: DSA-3439-1 Critical: Prosody Remote Access and Auth Flaws

CVE-2016-1231

Kim Alvefur discovered a flaw in Prosody's HTTP file-serving module
that allows it to serve requests outside of the configured public
root directory. A remote attacker can exploit this flaw to access
private files including sensitive data. The default configuration
does not enable the mod_http_files module and thus is not
vulnerable.

CVE-2016-1232

A remote attacker can take advantage of this flaw to guess at
probable values of the secret key and impersonate the affected
domain to other servers on the network.
