DESCRIPTION:
A vulnerability has been reported in various Horde products, which
can be exploited by malicious users to disclose sensitive information
and potentially compromise a vulnerable system.

Input passed to the "theme" parameter is not properly sanitised
before being used. This can be exploited to include arbitrary files
from local resources, using directory traversal attacks and
URL-encoded NULL bytes ("%00").

NOTE: Other attack vectors are also reported to exist.

Successful exploitation may allow execution of arbitrary code, but
requires valid user credentials.

The vulnerability is confirmed in Horde Application Framework 3.1.6
and also reported in Horde Groupware 1.0.4 and Horde Groupware
Webmail Edition 1.0.5. Prior versions may also be affected.

SOLUTION:
