CLA-2002:541-Conectiva Linux Security Announcement - mod_ssl

by Nikola Strahija on November 7th, 2002 "mod_ssl"[1] is a module for the Apache[2] web server which provides cryptography support. This module is included by default in the Apache package distributed with Conectiva Linux.


There is a cross site cripting vulnerability[3][4][5] in the mod_ssl
module. The "server name" field returned to the client was not being
filtered, which could lead to cross site scripting attacks if the
"UseCanonicalName" option is turned off (which is not the default)
and wildcard DNS is in use.


SOLUTION
All apache users should upgrade their packages.

IMPORTANT: it is necessary to manually restart the httpd server after
upgrading the packages if it was already running. In order to do
this, execute the following as root:

service httpd stop

(wait a few seconds and check with "ps ax|grep httpd" if there are
any httpd processes running. On a busy webserver this could take a
while)

service httpd start
