Debian: Security update for mapserver

Several vulnerabilities have been discovered in mapserver, a CGI-based web framework to publish spatial data and interactive mapping applications. Several instances of insufficient escaping of user input, leading to SQL injection attacks via OGC filter encoding (in WMS, WFS, and SOS filters). Missing length checks in the processing of OGC filter encoding that can lead to stack-based buffer overflows and the execution of arbitrary code. Updated packages are available from security.debian.org.
