lighttpd before 1.4.34, when SNI is enabled, configures weak SSL ciphers, which makes it easier for remote attackers to hijack sessions by inserting packets into the client-server data stream or obtain sensitive information by sniffing the network (CVE-2013-4508).

In lighttpd before 1.4.34, if setuid() fails for any reason, for instance if an environment limits the number of processes a user can have and the target uid already is at the limit, lighttpd will run as root. A user who can run CGI scripts could clone() often; in this case a lighttpd restart would end up with lighttpd running as root, and the CGI scripts would run as root too (CVE-2013-4559).

In lighttpd before 1.4.34, if "fam" is enabled and there are directories reachable from configured doc roots and aliases on which FAMMonitorDirectory fails, a remote client could trigger a DoS (CVE-2013-4560).
