Package : owncloud
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.
