CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE : mnogosearch
SUMMARY : Remote buffer overflow vulnerabilities
DATE : 2003-07-28 13:40:00
ID : CLA-2003:711
RELEVANT
RELEASES : 9

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 <[email protected]> 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 <[email protected]> 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.
