properly invalidate unauthenticated data (CVE-2014-0488), performs
incorrect verification of 304 replies (CVE-2014-0487) and does not
perform the checksum check when the Acquire::GzipIndexes option is
used (CVE-2014-0489).

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
