 * 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
> )
 * Two unspecified memory leaks. (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.");
