Rating: important
References: #555098 #627030 #661597 #663359 #690734 #713966

Cross-References: CVE-2011-3192
Affected Products:
SUSE Linux Enterprise Server 10 SP2
______________________________________________________________________________

An update that solves one vulnerability and has 5 fixes is
now available.

Description:


This update fixes a remote denial of service bug (memory
exhaustion) in the Apache 2 HTTP server, that could be
triggered by remote attackers using multiple overlapping
Request Ranges . (CVE-2011-3192)

The fix introduces a new config option: Allow MaxRanges
Number of ranges requested, if exceeded, the complete
content is served. default: 200 0|unlimited: unlimited
none: Range headers are ignored. (This option is a backport
from 2.2.21.)

It fixes also the minor security issue in the mod_cache
modules in the Apache HTTP Server that allowed remote
attackers to cause a denial of service (process crash) via
a request that lacks a path. (CVE-2010-1452)

It also fixes some non-security bugs: - take
LimitRequestFieldsize config option into account when
parsing headers from backend. Thereby avoid that the
receiving buffers are too small. bnc#690734. - add / when
on a directory to feed correctly linked listings.
bnc#661597 - a2enmod shalt not disable a module in query
mode. bnc#663359 - New option SSLRenegBufferSize fixes
"413 Request Entity Too Large occur" problem. - fixes
graceful restart hangs, bnc#555098.

______________________________________________________________________________

An update that solves one vulnerability and has four fixes
is now available. It includes one version update.

Description:


This update brings Apache to version 2.2.12.

The main reason is the enablement of the Server Name
Indication (SNI) that allows several SSL-enabled domains
on one IP address (FATE#311973). See the
SSLStrictSNIVHostCheck directive as documented in
/usr/share/apache2/manual/mod/mod_ssl.html.en

Also the patch for the ByteRange remote denial of service
attack (CVE-2011-3192) was refined and the configuration
options used by upstream were added.

Introduce new config option: Allow MaxRanges Number of
ranges requested, if exceeded, the complete content is
served. default: 200 0|unlimited: unlimited none: Range
headers are ignored. This option is a backport from 2.2.21.

Also fixed were

* CVE-2011-3348: Denial of service in proxy_ajp when
using a undefined method.
* CVE-2011-3368: Exposure of internal servers via
reverse proxy methods with mod_proxy enabled and incorrect
Rewrite or Proxy Rules.

This update also includes a newer
apache2-vhost-ssl.template, which disables SSLv2, and
allows SSLv3 and strong ciphers only. Please note that
existing vhosts will not be converted.
