prosody - security update

Two vulnerabilities were discovered in Prosody, a lightweight
Jabber/XMPP server. The Common Vulnerabilities and Exposures project
identifies the following issues:

• 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
  Thijs Alkemade discovered that Prosody’s generation of the secret
  token for server-to-server dialback authentication relied upon a
  weak random number generator that was not cryptographically secure.
  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.

For the oldstable distribution (wheezy), these problems have been fixed
in version 0.8.2-4+deb7u3.

For the stable distribution (jessie), these problems have been fixed in
version 0.9.7-2+deb8u2.

We recommend that you upgrade your prosody packages.
