Changes with Apache 2.4.41 *) SECURITY: CVE-2019-10081 (cve.mitre.org) mod_http2: HTTP/2 very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client. [Stefan Eissing] *) SECURITY: CVE-2019-9517 (cve.mitre.org) mod_http2: a malicious client could perform a DoS attack by flooding a connection with requests and basically never reading responses on the TCP connection. Depending on h2 worker dimensioning, it was possible to block those with relatively few connections. [Stefan Eissing] *) SECURITY: CVE-2019-10098 (cve.mitre.org) rewrite, core: Set PCRE_DOTALL flag by default to avoid unpredictable matches and substitutions with encoded line break characters. [Yann Ylavic] *) SECURITY: CVE-2019-10092 (cve.mitre.org) Remove HTML-escaped URLs from canned error responses to prevent misleading text/links being displayed via crafted links. [Eric Covener] *) SECURITY: CVE-2019-10097 (cve.mitre.org) mod_remoteip: Fix stack buffer overflow and NULL pointer deference when reading the PROXY protocol header. [Joe Orton, Daniel McCarney <cpu letsencrypt.org>] *) SECURITY: CVE-2019-10082 (cve.mitre.org) mod_http2: Using fuzzed network input, the http/2 session handling could be made to read memory after being freed, during connection shutdown. [Stefan Eissing] *) mod_proxy_balancer: Improve balancer-manager protection against XSS/XSRF attacks from trusted users. [Joe Orton, Niels Heinen <heinenn google.com>] *) mod_session: Introduce SessionExpiryUpdateInterval which allows to configure the session/cookie expiry's update interval. PR 57300. [Paul Spangler <paul.spangler ni.com>] *) modules/filters: Fix broken compilation when using old GCC (<4.2.x). PR 63633. [Rainer Jung, Joe Orton] *) mod_ssl: Fix startup failure in 2.4.40 with SSLCertificateChainFile configured for a domain managed by mod_md. [Stefan Eissing] Changes with Apache 2.4.40 *) core, mod_rewrite: Set PCRE_DOTALL by default. Revert via RegexDefaultOptions -DOTALL [Yann Ylavic] *) core: Remove request details from built-in error documents [Eric Covener] *) mod_http2: core setting "LimitRequestFieldSize" is not additionally checked on merged header fields, just as HTTP/1.1 does. [Stefan Eissing, Michael Kaufmann] *) mod_http2: fixed a bug that prevented proper stream cleanup when connection throttling was in place. Stream resets by clients on streams initiated by them are counted as possible trigger for throttling. [Stefan Eissing] *) mod_http2/mpm_event: Fixes the behaviour when a HTTP/2 connection has nothing more to write with streams ongoing (flow control block). The timeout waiting for the client to send WINODW_UPDATE was incorrectly KeepAliveTimeout and not Timeout as it should be. Fixes PR 63534. [Yann Ylavic, Stefan Eissing] *) mod_proxy_balancer: Load balancer required byrequests when bytraffic chosen. PR 62372. [Jim Jagielski] *) mod_proxy_hcheck: Create the configuration for mod_proxy_hcheck when used in BalancerMember. PR 60757. [Jean-Frederic Clere] *) mod_proxy_hcheck: Mute extremely frequent debug message. [Yann Ylavic] *) mod_ssl/mod_md: reversing dependency by letting mod_ssl offer hooks for adding certificates and keys to a virtual host. An additional hook allows answering special TLS connections as used in ACME challenges. Adding 2 new hooks for init/get of OCSP stapling status information when other modules want to provide those. Falls back to own implementation with same behaviour as before. [Stefan Eissing] *) mod_md: new features - protocol - supports the ACMEv2 protocol. It is the default and will be used on the next certificate renewal, unless another "MDCertificateAuthority" is configured - ACMEv2 endpoints use the GET via empty POST way of accessing resources, see announcement by Let's Encrypt: https://community.letsencrypt.org/t/acme-v2-scheduled-deprecation-of-unauthenticated-resource-gets/74380 - challenges - new challenge method 'tls-alpn-01' implemented - challenge type 'tls-sni-01' has been removed as CAs do not offer this any longer - supports command configuration to setup/teardown 'dns-01' challenges - supports wildcard certificates when dns challenges are configured - status information and monitoring - a domain exposes its status at https://<domain>/.httpd/certificate-status - Managed Domains are now in Apache's 'server-status' page - A new handler 'md-status' exposes verbose status information in JSON format - new directives - "MDCertificateFile" and "MDCertificateKeyFile" to configure a Managed Domain that uses static files. Auto-renewal is turned off for those. - "MDMessageCmd" that is invoked on several events: 'renewed', 'expiring' and 'errored'. - "MDWarnWindow" directive to configure when expiration warnings shall be issued. [Stefan Eissing] *) mod_mime_magic: Fix possible corruption of returned strings. [Christophe Jaillet] *) Default "conf/magic": Fix pattern for "audio/x-wav" for WAV files, remove "audio/unknown" pattern for other RIFF files. [Àngel Ollé Blázquez <aollebla redhat.com>] *) mod_proxy_http2: fixing a potential NULL pointer use in logging. [Christophe Jaillet, Dr Silvio Cesare InfoSect] *) mod_dav: Reduce the amount of memory needed when doing PROPFIND's on large collections by improving the memory management. [Joe Orton, Ruediger Pluem] *) mod_proxy_http2: adding support for handling trailers in both directions. PR 63502. [Stefan Eissing] *) mod_proxy_http: forward 100-continue, and minimize race conditions when reusing backend connections. PR 60330. [Yann Ylavic, Jean-Frederic Clere] *) mod_proxy_balancer: Fix some HTML syntax issues. [Christophe Jaillet] *) When using mod_status with the Event MPM, report the number of requests associated with an active connection in the "ACC" field. Previously zero was always reported with this MPM. PR60647. [Eric Covener] *) mod_http2: remove the no longer existing h2_ngn_shed.c from Cmake. [Stefan Eissing] *) mod_proxy/ssl: Proxy SSL client certificate configuration and other proxy SSL configurations broken inside <Proxy> context. PR 63430. [Ruediger Pluem, Yann Ylavic] *) mod_proxy: allow SSLProxyCheckPeer* usage for all proxy modules. PR 61857. [Markus Gausling <markusgausling googlemail.com>, Yann Ylavic] *) mod_reqtimeout: Fix default rates missing (not applied) in 2.4.39. PR 63325. [Yann Ylavic] *) mod_info: Fix output of server settings for PIPE_BUF in mod_info in the rare case that PIPE_BUF is defined. [Rainer Jung] *) mod_md: Store permissions are enforced on file creation, enforcing restrictions in spite of umask. Fixes <https://github.com/icing/mod_md/issues/117>. [Stefan Eissing]
