Did you mean zsh instead of bash?

} And I was referring to the zsh readme, changelog, git log.

The paragraph about "privilege escalation" quoted above appears at the
top of the README file.

Change log entry is this:

2014-09-29  Peter Stephenson  <p.stephenson@xxxxxxxxxxx>

        * users/19183: Src/hist.c: handle unlikely error case with
        fdopen() better.

        * 33276: Src/params.c, Src/zsh.h: safer import of numerical
        variables from environment.

The git log is very brief and is the same as the 33276 ChangeLog.

} Huh, I'll look again.

The first mention of the integer import problem on the list is here:
