"The version of MapServer hosted on the remote web server may be
affected by a SQL injection vulnerability due to a failure to properly
sanitize user-supplied input.  Specifically, the
mPostGISLayerSetTimeFilter function in mappostgis.c does not properly
sanitize user-supplied input passed via PostGIS TIME filters, leading to
a possible unintended disclosure of data. 

Note: In order for this vulnerability to be exploited, WMS-Time must be
configured and PostGIS must be in use.");
