    value:
"In httplib2, an attacker controlling unescaped part of uri for
`httplib2.Http.request()` could change request headers and body, send
additional hidden requests to same server. This vulnerability impacts
software that uses httplib2 with uri constructed by string
concatenation, as opposed to proper urllib building with escaping.

For Debian 8 'Jessie', this problem has been fixed in version
0.9+dfsg-2+deb8u1.

We recommend that you upgrade your python-httplib2 packages.

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
introducing additional issues."
