Apache 2.2.11釋出

全球最多網站主機使用的網頁伺服器軟體Apache HTTPD,在日前正式推出了安全性更新版本Apache 2.2.11,取代原先的2.2.10,修正的安全性問題主要都是2.2.10版以來的基礎,當中包括mod_rewrite、mod_proxy、mod_cache等幾項模組的修正。


Apache官方建議所有使用Apache網頁伺服器軟體的網站進行Apache HTTPD的更新。

Apache 2.2.11的更新列表,更新的內容如下:

Changes with Apache 2.2.11

*) core: When the ap_http_header_filter processes an error bucket, cleanup
the passed brigade before returning AP_FILTER_ERROR down the filter
chain. This unambiguously ensures the same error bucket isn't revisited
[Ruediger Pluem]

*) core: Error responses set by filters were being coerced into 500 errors,
sometimes appended to the original error response. Log entry of:
'Handler for (null) returned invalid result code -3'
[Eric Covener]

*) configure: Don't reject libtool 2.x
PR 44817 [Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA gmail.com>]

*) mod_autoindex: add configuration option to insert string
in HTML HEAD (IndexHeadInsert). [Nick Kew]

*) Add new LogFormat parameter, %k, which logs the number of
keepalive requests on this connection for this request.
PR 45762 [Dan Poirier <poirier pobox.com>, Jim Jagielski]

*) Export and install the mod_rewrite.h header to ensure the optional
rewrite_mapfunc_t and ap_register_rewrite_mapfunc functions are
available to third party modules. [Graham Leggett]

*) mod_cache: Convert age of cached object to seconds before comparing it to
age supplied by the request when checking whether to send a Warning
header for a stale response. PR 39713. [Owen Taylor <otaylor redhat.com>]

*) Build: Correctly set SSL_LIBS during openssl detection if pkgconfig is
not available. PR 46018 [Ruediger Pluem]

*) mod_proxy_ajp: Do not fail if response data is sent before all request
data is read. PR 45911 [Ruediger Pluem]

*) mod_proxy_balancer: Add in forced recovery for balancer members if
all are in error state. [Mladen Turk]

*) mod_proxy: Prevent segmentation faults by correctly adjusting the
lifetime of the buckets read from the proxy backend. PR 45792
[Ruediger Pluem]

*) mod_expires: Do not sets negative max-age / Expires header in the past.
PR 39774 [Jim Jagielski]

*) mod_info: Was displaying the wrong value for the KeepAliveTimeout
value. [Jim Jagielski]

*) mod_proxy_ajp: Fix wrongly formatted requests where client
sets Content-Length header, but doesn't provide a body.
Servlet container always expects that next packet is
body whenever C-L is present in the headers. This can lead
to wrong interpretation of the packets. In this case
send the empty body packet, so container can deal with
that. [Mladen Turk]

*) core: Add ap_timeout_parameter_parse to public API. [Ruediger Pluem]

*) mod_proxy: Add the possibility to set the worker parameters
connectiontimeout and ping in milliseconds. [Ruediger Pluem]

*) Worker MPM: Crosscheck that idle workers are still available before using
them and thus preventing an overflow of the worker queue which causes
a SegFault. PR 45605 [Denis Ustimenko <denusk gmail.com>]

*) Windows: Always build the odbc dbd driver on windows, to be consistent
with the apr-util default. [Tom Donovan]
