dhcp/0009-dhcp-4.2.6-close-on-exec.patch
Reinhard Max e9398b14d9 - Update to dhcp-4.3.6-P1: 
* CVE-2018-5733, bsc#1083303: reference count overflow in dhcpd.
  * CVE-2018-5732, bsc#1083302: buffer overflow bug in dhclient.
  * Plugged a socket descriptor leak in OMAPI
  * The server now allows the client identifier (option 61) to own
    leases in more than one subnet concurrently [ISC-Bugs #41358].
  * When replying to a DHCPINFORM, the server will now include
    options specified at the pool scope, provided the ciaddr field
    of the DHCPINFORM is populated.
    [ISC-Bugs #43219] [ISC-Bugs #45051].
  * When memory allocation fails in a repeated way the process
    writes "Run out of memory." on the standard error and exists
    with status 1  [ISC-Bugs #32744].
  * The new lmdb (Lightning Memory DataBase) bind9 configure
    option is now disabled by default to avoid the presence of
    this library to be detected which can lead to a link failure.
    [ISC-Bugs #45069]
  * The linux interface discovery code has been modified to use
    getifaddrs() as is done for BSD and OS-X.
    [ISC-Bugs #28761] and others.
  * Fixed a bug in OMAPI that causes omshell to crash when a
    name-value pair with a zero length value is shipped in an
    object [ISC-Bugs #29108].
  * On 64-bit platforms, dhclient now generates the correct value
    for the script environment variable, "expiry", the lease
    expiry value exceeds 0x7FFFFFFF [ISC-Bugs #43326].
  * Common timer logic was modified to cap the maximum timeout
    values at 0x7FFFFFFF - 1 [ISC-Bugs #28038].
  * DHCP6 FQDN option unpacking code now correctly handles values
    that contain spaces, special, or non-printable characters.
