lighttpd: upgrade 1.4.63 -> 1.4.64
0001-mod_extforward-fix-out-of-bounds-OOB-write-fixes-313.patch

with_gdbm, with_memcached
removed since they're not applicable in 1.4.64.
Changelog:
=========
Important changes
remove deprecated modules, bugfixes, CVE-2022-22707 (rare configs)
Behavior Changes
(previously announced and scheduled)
-graceful restart/shutdown timeout changed from 0 (disabled) to 8 seconds
configure an alternative with:
server.feature-flags += ("server.graceful-shutdown-timeout" => 8)
build: lighttpd defaults to -with-pcre2 instead of -with-pcre
pcre2 is current. pcre is no longer maintained.
Explicitly specify -with-pcre in build to use pcre instead of pcre2.
-deprecated modules (previously announced) have been removed
mod_authn_mysql
mod_mysql_vhost
mod_cml
mod_flv_streaming
mod_geoip
mod_trigger_b4_dl

Subject: [PATCH] [mod_extforward] fix out-of-bounds (OOB) write (fixes #3134)
|
||||
|
||||
(thx povcfe)
|
||||
|
||||
(edited: gstrauss)
|
||||
|
||||
There is a potential remote denial of service in lighttpd mod_extforward
|
||||
under specific, non-default and uncommon 32-bit lighttpd mod_extforward
|
||||
configurations.
|
||||
|
||||
Under specific, non-default and uncommon lighttpd mod_extforward
|
||||
configurations, a remote attacker can trigger a 4-byte out-of-bounds
|
||||
write of value '-1' to the stack. This is not believed to be exploitable
|
||||
in any way beyond triggering a crash of the lighttpd server on systems
|
||||
where the lighttpd server has been built 32-bit and with compiler flags
|
||||
which enable a stack canary -- gcc/clang -fstack-protector-strong or
|
||||
-fstack-protector-all, but bug not visible with only -fstack-protector.
|
||||
|
||||
With standard lighttpd builds using -O2 optimization on 64-bit x86_64,
|
||||
this bug has not been observed to cause adverse behavior, even with
|
||||
gcc/clang -fstack-protector-strong.
|
||||
|
||||
For the bug to be reachable, the user must be using a non-default
|
||||
lighttpd configuration which enables mod_extforward and configures
|
||||
mod_extforward to accept and parse the "Forwarded" header from a trusted
|
||||
proxy. At this time, support for RFC7239 Forwarded is not common in CDN
|
||||
providers or popular web server reverse proxies. It bears repeating that
|
||||
for the user to desire to configure lighttpd mod_extforward to accept
|
||||
"Forwarded", the user must also be using a trusted proxy (in front of
|
||||
lighttpd) which understands and actively modifies the "Forwarded" header
|
||||
sent to lighttpd.
|
||||
|
||||
lighttpd natively supports RFC7239 "Forwarded"
|
||||
hiawatha natively supports RFC7239 "Forwarded"
|
||||
|
||||
nginx can be manually configured to add a "Forwarded" header
|
||||
https://www.nginx.com/resources/wiki/start/topics/examples/forwarded/
|
||||
|
||||
A 64-bit build of lighttpd on x86_64 (not known to be affected by bug)
|
||||
in front of another 32-bit lighttpd will detect and reject a malicious
|
||||
"Forwarded" request header, thereby thwarting an attempt to trigger
|
||||
this bug in an upstream 32-bit lighttpd.
|
||||
|
||||
The following servers currently do not natively support RFC7239 Forwarded:
|
||||
nginx
|
||||
apache2
|
||||
caddy
|
||||
node.js
|
||||
haproxy
|
||||
squid
|
||||
varnish-cache
|
||||
litespeed
|
||||
|
||||
Given the general dearth of support for RFC7239 Forwarded in popular
|
||||
CDNs and web server reverse proxies, and given the prerequisites in
|
||||
lighttpd mod_extforward needed to reach this bug, the number of lighttpd
|
||||
servers vulnerable to this bug is estimated to be vanishingly small.
|
||||
Large systems using reverse proxies are likely running 64-bit lighttpd,
|
||||
which is not known to be adversely affected by this bug.
|
||||
|
||||
In the future, it is desirable for more servers to implement RFC7239
|
||||
Forwarded. lighttpd developers would like to thank povcfe for reporting
|
||||
this bug so that it can be fixed before more CDNs and web servers
|
||||
implement RFC7239 Forwarded.
