Linux bash exploit discovered
ewemoa:
I'm not sure what the current status is, but FWIW at some point Ubuntu was using dash as its default system shell:

Tuxman:
indeed, it is still the default login shell

:huh:

According to Gentoo's wiki:
As some sh scripts may have bashisms in them, it is not guaranteed to work out-of-the-box on Gentoo as /bin/sh replacement.

May be if that's still the case, there will be more incentive to make some appropriate changes...
OTOH, there's this:
https://bugs.gentoo.org/45735?id=45735
with the status RESOLVED CANTFIX
ewemoa:
I just checked a relatively recent version of Linux Mint (17 I think), and /bin/sh symlinked to dash, so my guess is that Ubuntu still uses dash as the system shell.
ewemoa:
Arch seems to have taken the position (at least at some point) of not switching:
We are using bash arrays and lots of other bash features, removing them now is simply impossible. bash it is, and will be.
