== httpd ==
 
 
''httpd'' was updated to 2.4.3-1. The new version has a lot of fixes and improvements:
 
 
* SECURITY: CVE-2012-3502  (cve.mitre.org) mod_proxy_ajp, mod_proxy_http: Fix an issue in back end connection closing which could lead to privacy issues due to a response mixup.
 
 
* SECURITY: CVE-2012-2687 (cve.mitre.org)  mod_negotiation: Escape filenames in variant list to prevent a possible XSS for a site where untrusted users can upload files to a location with MultiViews enabled.
 
 
* mod_authnz_ldap: Don't try a potentially expensive nested groups search before exhausting all AuthLDAPGroupAttribute checks on the current group.
 
 
* mod_lua: Add new directive LuaAuthzProvider to allow implementing an authorization provider in lua.
 
 
* core: Be less strict when checking whether Content-Type is set to "application/x-www-form-urlencoded" when parsing POST data, or we risk losing data with an appended charset.
 
 
* httpd.conf: Added configuration directives to set a bad_DNT environment variable based on User-Agent and to remove the DNT header field from incoming requests when a match occurs. This currently has the effect of removing DNT from requests by MSIE 10.0 because it deliberately violates the current specification of DNT semantics for HTTP.
 
 
 
* mod_cache: Set content type in case we return stale content.
 
 
* ab: Fix read failure when targeting SSL server.
 
 
* htpasswd: Use correct file mode for checking if file is writable.
 
 
* mod_rewrite: Fix crash with dbd RewriteMaps.
 
 
* mod_ssl: Add new directive SSLCompression to disable TLS-level compression.
 
 
* mod_lua: Add a few missing request_rec fields. Rename remote_ip to client_ip to match conn_rec.
 
 
* mod_lua: Change prototype of vm_construct, to work around gcc bug which causes a segfault.
 
 
* mpm_event: Don't count connections in lingering close state when calculating how many additional connections may be accepted.
 
 
* mod_ssl: If exiting during initialization because of a fatal error, log a message to the main error log pointing to the appropriate virtual host error log.
 
 
* mod_proxy_ajp: Reduce memory usage in case of many keep-alive requests on one connection.
 
 
* mod_proxy_balancer: Restore balancing after a failed worker has recovered when using lbmethod_bybusyness.
 
 
* mod_setenvif: Compile some global regex only once during startup. This should save some memory, especially with .htaccess.
 
 
* core: Add the port number to the vhost's name in the scoreboard.
 
 
* mod_proxy: Fix ProxyPassReverse for balancer configurations.
 
 
* mod_lua: Add the parsebody function for parsing POST data.
 
 
* apxs: Use LDFLAGS from config_vars.mk in addition to CFLAGS and CPPFLAGS.
 
 
* mod_proxy: Fix memory leak or possible corruption in ProxyBlock implementation.
 
 
* mod_proxy: Check hostname from request URI against ProxyBlock list, not forward proxy, if ProxyRemote* is configured.
 
 
* mod_proxy_connect: Avoid DNS lookup on hostname from request URI if ProxyRemote* is configured.
 
 
* mpm_event, mpm_worker: Remain active amidst prevalent child process resource shortages.
 
 
* Add "strict" and "warnings" pragmas to Perl scripts.
 
 
* ab: Fix bind() errors.
 
 
* mpm_event: Don't do a blocking write when starting a lingering close from the listener thread.
 
 
* mod_so: If a filename without slashes is specified for LoadFile or LoadModule and the file cannot be found in the server root directory, try to use the standard dlopen() search path.
 
 
* mpm_event, mpm_worker: Fix cases where the spawn rate wasn't reduced after child process resource shortages.
 
 
* mpm_prefork: Reduce spawn rate after a child process exits due to unexpected poll or accept failure.
 
 
* core: Log value of Status header line in script responses rather than the fixed header name.
 
 
* mpm_ssl: Fix handling of empty response from OCSP server.
 
 
* mpm_event: Fix handling of MaxConnectionsPerChild.
 
 
* mod_authz_core: If an expression in "Require expr" returns denied and references %{REMOTE_USER}, trigger authentication and retry.
 
 
* core: Always log if LimitRequestFieldSize triggers.
 
 
* mod_deflate: Skip compression if compression is enabled at SSL level.
 
 
* core: Add missing HTTP status codes registered with IANA.
 
 
* mod_ldap: Treat the "server unavailable" condition as a transient error with all LDAP SDKs.
 
 
* core: Fix spurious "not allowed here" error returned when the Options directive is used in .htaccess and "AllowOverride Options" (with no specific options restricted) is configured.
 
 
* mod_authz_core: Fix parsing of Require arguments in <AuthzProviderAlias>.
 
 
* mod_log_config: Fix %{abc}C truncating cookie values at first "=".
 
 
* mod_ext_filter: Fix error_log spam when input filters are configured. 
 
 
* mod_rewrite: Add "AllowAnyURI" option.
 
 
* htdbm, htpasswd: Don't crash if crypt() fails (e.g. with FIPS enabled).
 
 
* core: Use a TLS 1.0 close_notify alert for internal dummy connection if the chosen listener is configured for https.
 
 
* mod_proxy: Use the the same hostname for SNI as for the HTTP request when forwarding to SSL backends.
 
 
* mod_info: Display all registered providers.
 
 
* mod_ssl: Send the error message for speaking http to an https port using HTTP/1.0 instead of HTTP/0.9, and omit the link that may be wrong when using SNI.
 
 
* core: Fix segfault in logging if r->useragent_addr or c->client_addr is unset.
 
 
* log_server_status: Bring Perl style forward to the present, use standard modules, update for new format of server-status output.
 
 
* mod_sed, mod_log_debug, mod_rewrite: Symbol namespace cleanups.
 
 
* core: Prevent "httpd -k restart" from killing server in presence of config error.
 
 
* mod_proxy_fcgi: If there is an error reading the headers from the backend, send an error to the client.

''lighttpd'' was updated to 1.4.32-2. There are many fixes:
 
 
* [ssl] fix segfault in counting renegotiations for openssl versions without TLSEXT/SNI
 
 
* Move fdevent subsystem includes to implementation files to reduce conflicts
 
 
* [mod_compress] fix handling if etags are disabled but cache-dir is set – may lead to double response
