(CVE-2011-3607)

Prutha Parikh discovered that the mod_proxy module did not properly
interact with the RewriteRule and ProxyPassMatch pattern matches in the
configuration of a reverse proxy. This could allow remote attackers to
contact internal webservers behind the proxy that were not intended for
external exposure. (CVE-2011-4317)

Rainer Canavan discovered that the mod_log_config module incorrectly
handled a certain format string when used with a threaded MPM. A remote
attacker could exploit this to cause a denial of service via a specially-
crafted cookie. This issue only affected Ubuntu 11.04 and 11.10.
(CVE-2012-0021)

It was discovered that the Apache HTTP Server incorrectly handled certain
type fields within a scoreboard shared memory segment. A local attacker
could exploit this to cause a denial of service. (CVE-2012-0031)

Norman Hippert discovered that the Apache HTTP Server incorrectly handled
header information when returning a Bad Request (400) error page. A remote
attacker could exploit this to obtain the values of certain HTTPOnly
cookies. (CVE-2012-0053)");
