Synopsis ========
Lighttpd is vulnerable to the remote execution of arbitrary code.
Background ==========
Lighttpd is a lightweight HTTP web server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/lighttpd < 1.4.18 >= 1.4.18
Description ===========
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 ======
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.
Workaround ==========
Edit the file /etc/lighttpd/lighttpd.conf and comment the following line: "include mod_fastcgi.conf"
Resolution ==========
All Lighttpd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.18"
