<p>
|
|
Mattias Bengtsson and Philip Olausson have discovered a buffer overflow
|
|
vulnerability in the function fcgi_env_add() in the file mod_fastcgi.c
|
|
when processing overly long HTTP headers.
|
|
</p>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
A remote attacker could send a specially crafted request to the
|
|
vulnerable Lighttpd server, resulting in the remote execution of
|
|
arbitrary code with privileges of the user running the web server. Note
|
|
that mod_fastcgi is disabled in Gentoo's default configuration.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Edit the file /etc/lighttpd/lighttpd.conf and comment the following
|
|
line: "include mod_fastcgi.conf"
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Lighttpd users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.18"</code>
|
|
</resolution>
