SUMMARY   : Remote buffer overflow vulnerabilities

DESCRIPTION
 mnoGoSearch[1] is a full-featured web search engine software for
 intranet and internet servers.
 
 This update addresses two vulnerabilities in mnoGoSearch which affect
 Conectiva Linux 9:
 
 1. Buffer overflow in the "ul" variable (CAN-2003-0436)
 pokleyzz <pokleyzz@scan-associates.net> reported[2] a buffer overflow
 vulnerability in mnoGoSearch which can be exploited remotely to
 execute arbitrary commands with the privileges of the webserver.
 
 2. Buffer overflow in the query variable ("q") (CVE-2002-0789)
 qitest1 <qitest1@bespin.org> reported a buffer overflow
 vulnerability[3] in the query variable ("q") which can be exploited
 remotely to execute arbitrary commands with the privileges of the
 webserver.
 
 The packages available through this update contain the new version
 released by the authors that fixes these issues.
 
 Additionally, some other bugfixes and enhancements have been
 included:
 
 - the files are now placed in the webserver directory (/srv/www) and
 not in /var/www;
 
 - the CGI executable "search.cgi" is now installed in
 /srv/www/default/cgi-bin;
 
 - access to the "search.cgi" CGI executable is restricted by default
 to localhost (or 127.0.0.1). To change these permissions, please edit
 /etc/apache/conf/conf.d/mnogosearch.conf and restart Apache. This was
 done to avoid a possible unnecessary exposure of this service in the
 case the package was installed but not configured.
 
 - configuration files in the /etc/mnogosearch directory have now
 stricter access permissions in order to avoid exposure of their
 database access passwords;
 
 - two new subpackages have been created: mnogosearch-devel and
 mnogosearch-devel-static, used only for development purposes.


SOLUTION
 It is recommended that all mnoGoSearch users upgrade their packages.
