SECURITY UPDATE: content injection in http method (CVE-2019-3462)
This fixes a security issue that can be exploited to inject arbritrary debs
or other files into a signed repository as followed:
(1) Server sends a redirect to somewhere%0a<headers for the apt method> (where %0a is
\n encoded)
(2) apt method decodes the redirect (because the method encodes the URLs before
sending them out), writting something like
somewhere\n
<headers>
into its output
(3) apt then uses the headers injected for validation purposes.
