Description:

This update for lighttpd fixes the following issues:

lighttpd was updated to 1.4.66:

* a number of bug fixes
* Fix HTTP/2 downloads >= 4GiB
* Fix SIGUSR1 graceful restart with TLS
* futher bug fixes
* CVE-2022-37797: null pointer dereference in mod_wstunnel, possibly a
remotely triggerable crash (boo#1203358)
* In an upcoming release the TLS modules will default to using stronger,
modern chiphers and will default to allow client preference in selecting
ciphers. ???CipherString??? =>
???EECDH+AESGCM:AES256+EECDH:CHACHA20:SHA256:!SHA384???, ???Options???
=> ???-ServerPreference???
old defaults: ???CipherString??? => ???HIGH???, ???Options??? =>
???ServerPreference???
* A number of TLS options are how deprecated and will be removed in a
future release: ??? ssl.honor-cipher-order ??? ssl.dh-file ???
ssl.ec-curve ??? ssl.disable-client-renegotiation ??? ssl.use-sslv2 ???
ssl.use-sslv3 The replacement option is ssl.openssl.ssl-conf-cmd, but
lighttpd defaults should be prefered
* A number of modules are now deprecated and will be removed in a future
release: mod_evasive, mod_secdownload, mod_uploadprogress, mod_usertrack
can be replaced by mod_magnet and a few lines of lua.

update to 1.4.65:

* WebSockets over HTTP/2
* RFC 8441 Bootstrapping WebSockets with HTTP/2

* mod_accesslog option: accesslog.escaping = ???json???
* mod_deflate libdeflate build option
* speed up request body uploads via HTTP/2
* Behavior Changes
* change default server.max-keep-alive-requests = 1000 to adjust
* to increasing HTTP/2 usage and to web2/web3 application usage
* (prior default was 100)
* mod_status HTML now includes HTTP/2 control stream id 0 in the output
* which contains aggregate counts for the HTTP/2 connection
* (These lines can be identified with URL ???*???, part of ???PRI *???
