Bug#856169: Chromium installs a setuid binary without obvious need nor warning

control: retitle -1 chromium: switch to namespace sandbox

The sandbox is a necessary security feature.  A bug years ago doesn't
necessarily mean that it is faulty today.  There are lots of new
security bugs in chrome every few weeks, and rarely do they have to do
with the sandbox.

That said, there is a more modern sandboxing approach that uses
namespaces [0], but it is too late to change to it for stretch.

Best wishes,
Mike

Bug#856169: Chromium installs a setuid binary without obvious need nor warning

2017-02-25 Thread Alain Knaff
Package: chromium
Version: 56.0.2924.76-1~deb8u1

Chromium's .deb install a suid root binary
(/usr/lib/chromium/chrome-sandbox), potentially exposing the user's
system to hostile javascripts downloaded from the untrusted web.

This has already been exploited in the past:

https://bugs.chromium.org/p/chromium/issues/detail?id=76542

Debian packages should not expose users' systems to these kinds of risks
without informed consent.
