    CVE ID         : CVE-2015-3011 CVE-2015-3012 CVE-2015-3013
    
    Multiple vulnerabilities were discovered in ownCloud, a cloud storage
    web service for files, music, contacts, calendars and many more.
    
    CVE-2015-3011
    
        Hugh Davenport discovered that the "contacts" application shipped
        with ownCloud is vulnerable to multiple stored cross-site
        scripting attacks. This vulnerability is effectively exploitable
        in any browser.
    
    CVE-2015-3012
    
        Roy Jansen discovered that the "documents" application shipped with
        ownCloud is vulnerable to multiple stored cross-site scripting
        attacks. This vulnerability is not exploitable in browsers that
        support the current CSP standard.
    
    CVE-2015-3013
    
        Lukas Reschke discovered a blacklist bypass vulnerability, allowing
        authenticated remote attackers to bypass the file blacklist and
        upload files such as the .htaccess files. An attacker could leverage
        this bypass by uploading a .htaccess and execute arbitrary PHP code
        if the /data/ directory is stored inside the web root and a web
        server that interprets .htaccess files is used. On default Debian
        installations the data directory is outside of the web root and thus
        this vulnerability is not exploitable by default.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 7.0.4+dfsg-4~deb8u1.
    
    For the testing distribution (stretch), these problems have been fixed
    in version 7.0.4+dfsg-3.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 7.0.4+dfsg-3.
    
    We recommend that you upgrade your owncloud packages.
