Lighttpd is a lightweight HTTP web server.
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.
<impact type="high">
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.
Edit the file /etc/lighttpd/lighttpd.conf and comment the following
line: "include mod_fastcgi.conf"
All Lighttpd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-servers/lighttpd-1.4.18&quot;</code>
