Ok, the yakkety security update is finished so I uploaded 0.1.7 to the
xenial new queue.
** Changed in: bubblewrap (Ubuntu Xenial)
Status: Incomplete => In Progress
** Description changed:
- [SRU Team Note]
-
- This update is waiting on security bug 1657357 to be pushed first.
-
[Impact]
I'm writing a snapcraft plugin that uses bubblewrap for sandboxing
purposes, but since bubblewrap isn't available on xenial while snapcraft
is, it's currently blocked from landing.
Besides that, bubblewrap is a generally useful tool for running commands
in a sandbox, similar to a chroot, but can be run by an unprivileged
user, or like lxc, but more lightweight.
Bubblewrap is also needed to provide Flatpak on Ubuntu 16.04 LTS. Since
one major benefit of Flatpak is running newer apps on stable releases,
it's really beneficial to have Flatpak available on the latest Ubuntu
LTS.
[Test Case]
Type bwrap in a xenial terminal. The command isn't found.
[Regression Potential]
This package is already available in yakkety and zesty, and it depends
only on libc6 and libselinux1. It contains no services.
The bwrap binary is setuid root.
This is a new package for 16.04 and should not negatively affect any
other Ubuntu package.
[Other Info]
From the project page:
"The maintainers of this tool believe that it does not, even when used
in combination with typical software installed on that distribution,
allow privilege escalation. It may increase the ability of a logged in
user to perform denial of service attacks, however.
In particular, bubblewrap uses PR_SET_NO_NEW_PRIVS to turn off setuid
binaries, which is the traditional way to get out of things like
chroots."
Since snapd was backported to trusty-updates and not trusty-backports,
- we'd like to do the same with the Flatpak stack. (LP: #1656712)
+ we'd like to do the same (xenial-updates not xenial-backports) with the
+ Flatpak stack. (LP: #1656712)
