Changelog from 2.4.43 to 2.4.46
Changes with Apache 2.4.46
*) SECURITY: CVE-2020-11984 (cve.mitre.org)
mod_proxy_uwsgi: Malicious request may result in information disclosure
or RCE of existing file on the server running under a malicious process
environment. [Yann Ylavic]
*) SECURITY: CVE-2020-11993 (cve.mitre.org)
mod_http2: when throttling connection requests, log statements
where possibly made that result in concurrent, unsafe use of
a memory pool. [Stefan Eissing]
*) SECURITY:
mod_http2: a specially crafted value for the 'Cache-Digest' header
request would result in a crash when the server actually tries
to HTTP/2 PUSH a resource afterwards.
[Stefen Eissing, Eric Covener, Christophe Jaillet]
*) mod_proxy_fcgi: Fix build warnings for Windows platform
Changes with Apache 2.4.45
*) mod_http2: remove support for abandoned http-wg draft
<https://datatracker.ietf.org/doc/draft-kazuho-h2-cache-digest/>.
[Stefan Eissing]
Changes with Apache 2.4.44
*) mod_proxy_uwsgi: Error out on HTTP header larger than 16K (hard
protocol limit). [Yann Ylavic]
*) mod_http2:
Fixes <https://github.com/icing/mod_h2/issues/200>:
"LimitRequestFields 0" now disables the limit, as documented.
Fixes <https://github.com/icing/mod_h2/issues/201>:
Do not count repeated headers with same name against the field
count limit. The are merged internally, as if sent in a single HTTP/1 line.
[Stefan Eissing]
*) mod_http2: Avoid segfaults in case of handling certain responses for
already aborted connections. [Stefan Eissing, Ruediger Pluem]
*) mod_http2: The module now handles master/secondary connections and has marked
methods according to use. [Stefan Eissing]
*) core: Drop an invalid Last-Modified header value coming
from a FCGI/CGI script instead of replacing it with Unix epoch.
[Yann Ylavic, Luca Toscano]
*) Add support for strict content-length parsing through addition of
ap_parse_strict_length() [Yann Ylavic]
*) mod_proxy_fcgi: ProxyFCGISetEnvIf unsets variables when expression
evaluates to false. PR64365. [Michael König <mail ikoenig.net>]
*) mod_proxy_http: flush spooled request body in one go to avoid
leaking (or long lived) temporary file. PR 64452. [Yann Ylavic]
*) mod_ssl: Fix a race condition and possible crash when using a proxy client
certificate (SSLProxyMachineCertificateFile).
[Armin Abfalterer <a.abfalterer gmail.com>]
*) mod_ssl: Fix memory leak in stapling code. PR63687. [Stefan Eissing]
*) mod_http2: Fixed regression that no longer set H2_STREAM_ID and H2_STREAM_TAG.
PR64330 [Stefan Eissing]
*) mod_http2: Fixed regression that caused connections to close when mod_reqtimeout
was configured with a handshake timeout. Fixes gitub issue #196.
[Stefan Eissing]
*) mod_proxy_http2: the "ping" proxy parameter
(see <https://httpd.apache.org/docs/2.4/mod/mod_proxy.html>) is now used
when checking the liveliness of a new or reused h2 connection to the backend.
With short durations, this makes load-balancing more responsive. The module
will hold back requests until ping conditions are met, using features of the
HTTP/2 protocol alone. [Ruediger Pluem, Stefan Eissing]
*) core: httpd is no longer linked against -lsystemd if mod_systemd
is enabled (and built as a DSO). [Rainer Jung]
*) mod_proxy_http2: respect ProxyTimeout settings on backend connections
while waiting on incoming data. [Ruediger Pluem, Stefan Eissing]
[Apache 2.3.0-dev includes those bug fixes and changes with the
Apache 2.2.xx tree as documented, and except as noted, below.]
