Name : lighttpd Product : Fedora 19 Version : 1.4.32 Release : 1.fc19 URL : http://www.lighttpd.net/ Summary : Lightning fast webserver with light system requirements Description : Secure, fast, compliant and very flexible web-server which has been optimized for high-performance environments. It has a very low memory footprint compared to other webservers and takes care of cpu-load. Its advanced feature-set (FastCGI, CGI, Auth, Output-Compression, URL-Rewriting and many more) make it the perfect webserver-software for every server that is suffering load problems. -------------------------------------------------------------------------------- Update Information: One important denial of service (in 1.4.31) fix: CVE-2012-5533. A flaw was found in lighttpd version 1.4.31 that could be exploited by a remote user to cause a denial of service condition in lighttpd. A client could send a malformed Connection header to lighttpd (such as "Connection: TE,,Keep-Alive"), which would cause lighttpd to enter an endless loop, detecting an empty token but not incrementing the current string position, causing it to continually read ',' over and over. This flaw was introduced in 1.4.31 [1] when an "invalid read" bug was fixed [2].
