    Package        : prosody
    CVE ID         : CVE-2016-1231 CVE-2016-1232
    
    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.
