All supported architectures
Multiple stack-based buffer overflows in mod_alias and mod_rewrite can allow
execution of arbitrary code and cause a denial of service, and a bug in the
way mod_cgid handles CGI redirect paths could result in CGI output going to
the wrong client.
The Apache HTTP Server is one of the most popular web servers on the
Multiple stack-based buffer overflows in mod_alias and mod_rewrite allow
attackers who can create or edit configuration files including .htaccess
files, to cause a denial of service and execute arbitrary code via a regular
expression containing more than 9 captures, and a bug in the way mod_cgid
handles CGI redirect paths could result in CGI output going to the wrong
client when a threaded MPM is used, resulting in an information disclosure.
An attacker may cause a denial of service or execute arbitrary code with the
privileges of the user that is running apache.
There is no known workaround at this time.
It is recommended that all Gentoo Linux users who are running
net-misc/apache 2.x upgrade:
Code Listing 3.1: Resolution
# emerge sync
# emerge -pv '>=www-servers/apache-2.0.48'
# emerge '>=www-servers/apache-2.0.48'
# emerge clean
# /etc/init.d/apache2 restart
Please remember to update your config files in /etc/apache2 as --datadir has
been changed to /var/www/localhost.
