Subject: Re: strings / libbfd crasher

I do have a bunch more that seem exploitable, though - for example: - does this repro for
people (I tried with binutils 2.24)?

I think that given the expectations people have around what strings
does and whether it's safe to run on untrusted binaries, I'd seriously
question the wisdom of making it use libbfd, at least by default;
perhaps distros want to consider non-upstream patches that default to
the -a mode, instead?

I don't understand the user benefit of extracting strings only from
certain sections of executables, and I almost feel like it's a side
effect of strings being a part of binutils more than anything else.
