<description>
<p>
Julien Cayzax discovered that an insecure default setting exists in
mod_userdir in lighttpd. When userdir.path is not set the default value
used is $HOME. It should be noted that the "nobody" user's $HOME is "/"
(CVE-2008-1270). An error also exists in the SSL connection code which
can be triggered when a user prematurely terminates his connection
(CVE-2008-1531).
</p>
</description>
<impact type="normal">
<p>
A remote attacker could exploit the first vulnerability to read
arbitrary files. The second vulnerability can be exploited by a remote
attacker to cause a Denial of Service by terminating a victim's SSL
connection.
</p>
</impact>
<workaround>
<p>
As a workaround for CVE-2008-1270 you can set userdir.path to a
sensible value, e.g. <i>"public_html"</i>.
</p>
</workaround>
<resolution>
<p>
All lighttpd users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-servers/lighttpd-1.4.19-r2&quot;</code>
</resolution>
