A vulnerability has been discovered in lighttpd which could result in denial of service.
|Package||www-servers/lighttpd on all architectures|
|Affected versions||< 1.4.67|
|Unaffected versions||>= 1.4.67|
Lighttpd is a lightweight high-performance web server.
Lighttpd's mod_wstunnel does not initialize a handler function pointer if an invalid HTTP request (websocket handshake) is received.
An attacker can trigger a denial of service via making Lighttpd try to call an uninitialized function pointer.
There is no known workaround at this time.
All lighttpd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.67"
