Debian: DSA-2452-1: apache2 security update
Summary
- - If some front-end server on the same host forwards connections to an
apache2 backend server on the localhost address, or
- - if the machine running apache2 is also used for web browsing.
Systems not meeting one of these two conditions are not known to be
vulnerable. The actual security impact depends on which packages (and
accordingly which example scripts) are installed on the system.
Possible issues include cross site scripting, code execution, or
leakage of sensitive data.
This updates removes the problematic configuration sections from the
files /etc/apache2/sites-available/default and .../default-ssl. When
upgrading, you should not blindly allow dpkg to replace those files,
though. Rather you should merge the changes, namely the removal of the
'Alias /doc "/usr/share/doc"' line and the related '
You may also want to check if you have copied these sections to any
additional virtual host configurations.
For the stable distribution (squeeze), this problem has been fixed in
version 2.2.16-6+squeeze7.
For the testing distribution (wheezy), this problem will be fixed in
version 2.2.22-4.
For the unstable distribution (sid), this problem will be fixed in
version 2.2.22-4.
For the experimental distribution, this problem has been fixed in
version 2.4.1-3.
We recommend that you upgrade your apache2 packages and adjust your
configuration.
