Package: pbuilder
Version: 0.206
Tags: patch
Followup-For: Bug #579028
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
Dear Maintainer,
The attached patch changes the defaults to always enforce signed
repositories and aborts if an untrusted/manipulated package is
installed. It adds the new option --keyring (APTKEYRINGS) to add
additional keyrings, which are then used to verify the (local)
signed repositories. This way no untrusted packages can be
installed.
To still allow untrusted/unsigned repositories - they are a very
bad idea and allow remote attackers performing a MITM to take
over the system, including all built packages - the new option
- --allow-untrusted (ALLOWUNTRUSTED) was added.
I tested it with the official Debian repository, signed and
unsigned local repositories and it works fine for me. But I'm
only a "normal" pbuilder user, so I might have missed something.
Please test the patch.
I haven't tested it with cdebootstrap, but it should work as
well.
The old PBUILDERSATISFYDEPENDSOPT --check-key option was
deprecated and is no longer used (it emits a warning now) as
validation is the default now.
The patch also contains documentation updates for the new
options/variables and updates for the NEWS file describing the
necessary changes to continue using untrusted packages (but
please don't do that - especially as a Debian developer).
Please have a look and include the patch as soon as possible to
fix this security issue.
Regards,
Simon

Hi,
I talked to Junichi and he told me it was fine if I NMU'ed pbuilder to fix these
bugs. This is the debdiff for my NMU.

By unsetting APTGETOPT, and setting
PBUILDERSATISFYDEPENDSOPT=('--check-key'), the user now has an option
of verifying the key signature of each package against the installed
keyring.
|
|
|
|
| |
Make pbuilder-satisfydepends-aptitude and -classic relocatable.
|
|
|
|
|
| |
Add get_build_deps() and get_build_conflicts() functions wrapping
get_control_re() for BD_REGEXP and BC_REGEXP over DEBIAN_CONTROL.
|
|
|
|
|
|
|
|
| |
Only install aptitude in pbuilder-createbuildenv or
pbuilder-updatebuildenv, not in pbuilder-satisfydepends-aptitude, and
only when $PBUILDERSATISFYDEPENDSCMD uses aptitude. Remove aptitude in
pbuilder-createbuildenv and pbuilder-updatebuildenv otherwise;
closes: #539578.

It's probably not too useful when used non-interactively, and clutters output.

$Id$ is a CVS-specific feature which was useful for showing the version number of pbuilder, but is no longer relevant.
Something else is required for git, but that will need to be fixed later.
