- Update to 2.2.22

Addresses:
* SECURITY: CVE-2011-3607 (cve.mitre.org)
Integer overflow in the ap_pregsub function in server/util.c in the Apache HTTP
Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif
module is enabled, allows local users to gain privileges via a .htaccess file
with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request
header, leading to a heap-based buffer overflow.

* SECURITY: CVE-2012-0021 (cve.mitre.org)
The log_cookie function in mod_log_config.c in the mod_log_config module in the
Apache HTTP Server 2.2.17 through 2.2.21, when a threaded MPM is used, does not
properly handle a %{}C format string, which allows remote attackers to cause a
denial of service (daemon crash) via a cookie that lacks both a name and a
value.

* SECURITY: CVE-2012-0031 (cve.mitre.org)
scoreboard.c in the Apache HTTP Server 2.2.21 and earlier might allow local
users to cause a denial of service (daemon crash during shutdown) or possibly
have unspecified other impact by modifying a certain type field within a
scoreboard shared memory segment, leading to an invalid call to the free
function.

* SECURITY: CVE-2011-4317 (cve.mitre.org)
The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x
through 2.0.64, and 2.2.x through 2.2.21, when the Revision 1179239 patch is in
place, does not properly interact with use of (1) RewriteRule and (2)
ProxyPassMatch pattern matches for configuration of a reverse proxy, which
allows remote attackers to send requests to intranet servers via a malformed URI
containing an @ (at sign) character and a : (colon) character in invalid
positions. NOTE: this vulnerability exists because of an incomplete fix for
CVE-2011-3368.

* SECURITY: CVE-2012-0053 (cve.mitre.org)
protocol.c in the Apache HTTP Server 2.2.x through 2.2.21 does not properly
restrict header information during construction of Bad Request (aka 400) error
documents, which allows remote attackers to obtain the values of HTTPOnly
cookies via vectors involving a (1) long or (2) malformed header in conjunction
with crafted web script.

* SECURITY: CVE-2011-3368 (cve.mitre.org)
The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x
through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with use of
(1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a
reverse proxy, which allows remote attackers to send requests to intranet
servers via a malformed URI containing an initial @ (at sign) character.
