DESCRIPTION:
A vulnerability has been discovered in bozohttpd, which can be
exploited by malicious people to bypass certain security
restrictions.

The vulnerability is caused due to the server not properly handling
requests to a user's "public_html" folder while the folder does not
exist. This can be exploited to e.g. determine the existence of a
user and potentially disclose the user's files.

The vulnerability is confirmed in versions 20090522 and 20100509.
Other versions may also be affected.

SOLUTION:
Update to version 20100621.
