DESCRIPTION:
Two vulnerabilities have been reported in Koha, which can be
exploited by malicious people to disclose sensitive information.

1) Input passed to the "KohaOpacLanguage" cookie value in
cgi-bin/koha/opac-main.pl is not properly sanitised before being used
to include files. This can be exploited to include arbitrary files
from local resources via directory traversal attacks and URL-encoded
NULL bytes.

2) Input passed via the "Referer" HTTP header to help.pl is not
properly sanitised before being used to include files. This can be
exploited to include arbitrary files from local resources via
directory traversal attacks and URL-encoded NULL bytes.

The vulnerabilities are reported in 3.4.x versions prior to 3.4.7 and
3.6.x versions prior to 3.6.1.

SOLUTION:
Update to version 3.4.7 or 3.6.1.

PROVIDED AND/OR DISCOVERED BY:
Reported within Koha bug reports by Frère Sébastien Marie.
