CONECTIVA LINUX SECURITY ANNOUNCEMENT 
- --------------------------------------------------------------------------

PACKAGE   : mod_python
SUMMARY   : Remote denial of service vulnerability
DATE      : 2004-04-12 15:06:00
ID        : CLA-2004:837
RELEVANT
RELEASES  : 8, 9

- -------------------------------------------------------------------------

DESCRIPTION
 The package mod_python provides an Apache module that embeds the
 Python interpreter within the server.
 
 This update fixes a remote denial of service vulnerabiliy[1] in
 Apache web-servers which have mod_python enabled (this is not the
 default in Conectiva Linux). An attacker can crash an apache child
 process by sending a specially crafted message that triggers the bug
 in mod_python.
 
 The Common Vulnerabilities and Exposures project (cve.mitre.org) has
 assigned the name CAN-2003-0973 to this issue[2].


SOLUTION
 All mod_python users should do the upgrade. Notice that after the
 installation you have to restart the httpd service manually in order
 to load the new module. To achieve this you may execute the following
 command (as root):
 
 # service httpd restart
