DESCRIPTION
thttpd is a very simple and compact HTTP server.

The thttpd package distributed with Conectiva Linux 9
(thttpd-2.20c-22870cl) contains several bugs[1] that prevent it from
being useful. This update fixes these bugs and the following security
vulnerabilities that affect thttpd 2.20c (descriptions borrowed from
the respectives CVE pages):

- Sensitive files disclosure vulnerability[2] (CAN-2001-0892)
With the chroot option enabled, thttpd allows remote attackers to
view sensitive files under the document root (such as .htpasswd) via
a GET request with a trailing '/.'.

- Cross-site scripting vulnerability[3] (CVE-2002-0733)
thttpd allows remote attackers to execute arbitrary scripts via a URL
to a nonexistent page, which causes thttpd to insert the script into
a 404 error message.

- Directory traversal vulnerability[4] (CAN-2002-1562)
When using virtual hosting, thttpd allows remote attackers to read
arbitrary files via '..' (dot dot) sequences in the 'Host:' header.

The thttpd package has been updated to the "2.24" version, the latest
stable one available at this time.

SOLUTION
Users should install the new packages if they want to use thttpd.
