Upstream update.  Fixes a CVE:

  gzip -d could segfault and/or clobber the stack, possibly leading to
  arbitrary code execution.  This affects x86_64 but not 32-bit systems.
  This fixes CVE-2010-0001.
  For more details, see http://bugzilla.redhat.com/554418

  gzip -d would fail with a CRC error for some valid inputs.
  So far, the only valid input known to exhibit this failure was
  compressed "from FAT filesystem (MS-DOS, OS/2, NT)".  In addition,
  to trigger the failure, your memcpy implementation must copy in
  the "reverse" order.

Signoff both,
