VCLD-67-000027 - VAMI must protect against or limit the effects of HTTP types of denial-of-service (DoS) attacks.
Information
In UNIX and related computer operating systems, a file descriptor is an indicator used to access a file or other input/output resource, such as a pipe or network connection. File descriptors index into a per-process file descriptor table maintained by the kernel, which in turn indexes into a system-wide table of files opened by all processes, called the file table.As a single-threaded server, Lighttpd must be limited in the number of file descriptors that can be allocated. This will prevent Lighttpd from being used in a form of DoS attack against the operating system.
Solution
Navigate to and open /opt/vmware/etc/lighttpd/lighttpd.conf.Add or reconfigure the following value:
server.max-fds = 2048
