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.
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 ">=www-servers/lighttpd-1.4.18"
OS | Version | Architecture | Package | Version | Filename |
