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"
