   An update that fixes two vulnerabilities is now available.

Description:


   This update of dhcp fixes two security vulnerabilities:

   * Malformed client identifiers could cause a Denial of
   Service (excessive CPU consumption), effectively causing
   further client requests to not be processed anymore.
   (CVE-2012-3571
   <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3571
   > )
   * Two unspecified memory leaks. (CVE-2012-3954
   <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3954
   > )

   Additionally, the following issues were fixed:

   * The init script of dhcp-server was fixed to check
   syntax and fail on force-reload and restart to avoid
   stopping of running daemon followed by start failure
   * Added libgcc_s.so to chroot, so the server can report
   an assert/crash line.
