Changes with Apache 2.4.49 *) SECURITY: CVE-2021-40438 (cve.mitre.org) mod_proxy: Server Side Request Forgery (SSRF) vulnerabilty [Yann Ylavic] *) SECURITY: CVE-2021-39275 (cve.mitre.org) core: ap_escape_quotes buffer overflow *) SECURITY: CVE-2021-36160 (cve.mitre.org) mod_proxy_uwsgi: Out of bound read vulnerability [Yann Ylavic] *) SECURITY: CVE-2021-34798 (cve.mitre.org) core: null pointer dereference on malformed request *) SECURITY: CVE-2021-33193 (cve.mitre.org) mod_http2: Request splitting vulnerability with mod_proxy [Stefan Eissing] *) core/mod_proxy/mod_ssl: Adding `outgoing` flag to conn_rec, indicating a connection is initiated by the server to somewhere, in contrast to incoming connections from clients. Adding 'ap_ssl_bind_outgoing()` function that marks a connection as outgoing and is used by mod_proxy instead of the previous optional function `ssl_engine_set`. This enables other SSL module to secure proxy connections. The optional functions `ssl_engine_set`, `ssl_engine_disable` and `ssl_proxy_enable` are now provided by the core to have backward compatibility with non-httpd modules that might use them. mod_ssl itself no longer registers these functions, but keeps them in its header for backward compatibility. The core provided optional function wrap any registered function like it was done for `ssl_is_ssl`. [Stefan Eissing] *) mod_ssl: Support logging private key material for use with wireshark via log file given by SSLKEYLOGFILE environment variable. Requires OpenSSL 1.1.1. PR 63391. [Joe Orton] *) mod_proxy: Do not canonicalize the proxied URL when both "nocanon" and "ProxyPassInterpolateEnv On" are configured. PR 65549. [Joel Self <joelself gmail.com>] *) mpm_event: Fix children processes possibly not stopped on graceful restart. PR 63169. [Joel Self <joelself gmail.com>] *) mod_proxy: Fix a potential infinite loop when tunneling Upgrade(d) protocols from mod_proxy_http, and a timeout triggering falsely when using mod_proxy_wstunnel, mod_proxy_connect or mod_proxy_http with upgrade= setting. PRs 65521 and 65519. [Yann Ylavic] *) mod_unique_id: Reduce the time window where duplicates may be generated PR 65159 [Christophe Jaillet] *) mpm_prefork: Block signals for child_init hooks to prevent potential threads created from there to catch MPM's signals. [Ruediger Pluem, Yann Ylavic] *) Revert "mod_unique_id: Fix potential duplicated ID generation under heavy load. PR 65159" added in 2.4.47. This causes issue on Windows. [Christophe Jaillet] *) mod_proxy_uwsgi: Fix PATH_INFO setting for generic worker. [Yann Ylavic] *) mod_md: Certificate/keys pairs are verified as matching before a renewal is accepted as successful or a staged renewal is replacing the existing certificates. This avoid potential mess ups in the md store file system to render the active certificates non-working. [@mkauf] *) mod_proxy: Faster unix socket path parsing in the "proxy:" URL. [Yann Ylavic] *) mod_ssl: tighten the handling of ALPN for outgoing (proxy) connections. If ALPN protocols are provided and sent to the remote server, the received protocol selected is inspected and checked for a match. Without match, the peer handshake fails. An exception is the proposal of "http/1.1" where it is accepted if the remote server did not answer ALPN with a selected protocol. This accomodates for hosts that do not observe/support ALPN and speak http/1.x be default. *) mod_proxy: Fix possible reuse/merging of Proxy(Pass)Match worker instances with others when their URLs contain a '$' substitution. PR 65419 + 65429. [Yann Ylavic] *) mod_dav: Add method_precondition hook. WebDAV extensions define conditions that must exist before a WebDAV method can be executed. This hook allows a WebDAV extension to verify these preconditions. [Graham Leggett] *) Add hooks deliver_report and gather_reports to mod_dav.h. Allows other modules apart from versioning implementations to handle the REPORT method. [Graham Leggett] *) Add dav_get_provider(), dav_open_lockdb(), dav_close_lockdb() and dav_get_resource() to mod_dav.h. [Graham Leggett] *) core: fix ap_escape_quotes substitution logic. [Eric Covener] *) Easy patches: synch 2.4.x and trunk - mod_auth_basic: Use ap_cstr_casecmp instead of strcasecmp. - mod_ldap: log and abort locking errors. - mod_ldap: style fix for r1831165 - mod_ldap: build break fix for r1831165 - mod_deflate: Avoid hard-coded "%ld" format strings in mod_deflate's logging statements - mod_deflate: Use apr_uint64_t instead of uint64_t (follow up to r1849590) - mod_forensic: Follow up to r1856490: missing one mod_log_forensic test_char_table case. - mod_rewrite: Save a few cycles. - mod_request: Fix a comment (missing '_' in 'keep_body') and some style issues - core: remove extra whitespace in HTTP_NOT_IMPLEMENTED [Christophe Jaillet] *) core/mpm: add hook 'child_stopping` that gets called when the MPM is stopping a child process. The additional `graceful` parameter allows registered hooks to free resources early during a graceful shutdown. [Yann Ylavic, Stefan Eissing] *) mod_proxy: Fix icomplete initialization of BalancerMember(s) from the balancer-manager, which can lead to a crash. [Yann Ylavic] *) mpm_event: Fix graceful stop/restart of children processes if connections are in lingering close for too long. [Yann Ylavic] *) mod_md: fixed a potential null pointer dereference if ACME/OCSP server returned 2xx responses without content type. Reported by chuangwen. [chuangwen, Stefan Eissing] *) mod_md: - Domain names in `<MDomain ...>` can now appear in quoted form. - Fixed a failure in ACME challenge selection that aborted further searches when the tls-alpn-01 method did not seem to be suitable. - Changed the tls-alpn-01 setup to only become unsuitable when none of the dns names showed support for a configured 'Protocols ... acme-tls/1'. This allows use of tls-alpn-01 for dns names that are not mapped to a VirtualHost. [Stefan Eissing] *) Add CPING to health check logic. [Jean-Frederic Clere] *) core: Split ap_create_request() from ap_read_request(). [Graham Leggett] *) core, h2: common ap_parse_request_line() and ap_check_request_header() code. [Yann Ylavic] *) core: Add StrictHostCheck to allow unconfigured hostnames to be rejected. [Eric Covener] *) htcacheclean: Improve help messages. [Christophe Jaillet]
