DESCRIPTION:
Multiple vulnerabilities have been reported in ownCloud, which can be
exploited by malicious users to compromise a vulnerable system and
malicious people to conduct cross-site scripting attacks.

1) Input passed via the filename to
apps/files_versions/js/versions.js and apps/files/js/filelist.js and
event title to 3rdparty/fullcalendar/js/fullcalendar.js 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.

This vulnerability is reported in version 4.5.0 and versions prior to
4.0.9.

2) Certain unspecified input passed to
apps/user_webdavauth/settings.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.

3) An error due to the lib/migrate.php script not properly verifying
uploaded files can be exploited to execute arbitrary PHP code by
uploading a malicious mount.php file within a ZIP file.

Vulnerabilities #2 and #3 are reported in versions prior to 4.5.2.

4) An error due to the lib/filesystem.php script not properly
verifying uploaded files can be exploited to execute arbitrary PHP
code by uploading a malicious PHP file with a specially crafted
filename.

This vulnerability is reported in versions prior to 4.5.2 and 4.0.9.

SOLUTION:
Update to version 4.5.2.
