DESCRIPTION:
A security issue and two vulnerabilities have been reported in
ownCloud, which can be exploited by malicious users to bypass certain
security restrictions and by malicious people to conduct cross-site
scripting and cross-site request forgery attacks.

1) An error when returning a file handle for WebDAV requests within
the "fopen()" function (apps/files_sharing/sharedstorage.php) can be
exploited to modify a shared file of another user.

Successful exploitation requires "Enable Files Versioning" to be
disabled (enabled by default).

2) The application allows users to perform certain actions via HTTP
requests without performing proper validity checks to verify the
requests. This can be exploited to perform certain actions when a
logged-in user visits a specially crafted web page.

3) Input passed via the "token" parameter (when "app" is set to
"gallery" and "getfile" is set to "sharing.php") is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

The security issue and the vulnerabilities are reported in version
4.0.6. Other versions may also be affected.

SOLUTION:
Fixed in the GIT repository.

PROVIDED AND/OR DISCOVERED BY:
1) Reported by Fuddl within a Debian bug report.
2) Reported by the vendor.
3) Julien Cayssol
