LinuxSecurity.com: In DSA-1603-1, Debian released an update to the BIND 9 domain name server, which introduced UDP source port randomization to mitigate the threat of DNS cache poisoning attacks (identified by the Common Vulnerabilities and Exposures project as CVE-2008-1447)
POLICYGENTOOL(1) Debian GNU/Linux manual POLICYGENTOOL(1)NAME
policygentool - Interactive SELinux policy generation tool
SYNOPSIS
policygentool [options] <Module Name> <full path for application binary file>
DESCRIPTION
This tool generate three files for policy development, A Type Enforcement (te) file, a File Context (fc), and a Interface File(if). Most
of the policy rules will be written in the te file. Use the File Context file to associate file paths with security context. Use the
interface rules to allow other protected domains to interact with the newly defined domains.
The tool prompts for locations of pidfiles, any logfiles, files in /var/lib, and any init scripts, and whether any network access is desir-
able for the application. The tool then generates the appropriate policy rules for the module. After these files have been generated, the
make files for the appropriate SELinux policy, namely, /usr/share/selinux/refpolicy-targeted/include/Makefile or /usr/share/selinux/refpol-
icy-strict/include/Makefile can be used to compile the SELinux policy policy package. The resulting policy package can be loaded using
semodule.
