|
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).
|
|

<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 ">=www-servers/lighttpd-1.4.19-r2"</code>
|
|
</resolution>
