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.
