I think I would dispute that fedora is affected by this, referencing my comment in the upstream bug, https://bugs.freedesktop.org/show_bug.cgi?id=89129 ----------------------------- The code has diverged a bit in git so the proposed debian patch no longer applies. But good news: the current code should be safe(r), since all uses of local $var are initialized to avoid the problem, in particular, the code closest to what this patch touches now contains: search_desktop_file() { local default="$1" local dir="$2" local arg="$3" local file="" # look for both vendor-app.desktop, vendor/app.desktop ... Lastly, with test case given in debian report, I cannot reproduce, at least not with the versions of bash and dash shipped with fedora 20: $ cat testme testme() { x=backfromthedead local x echo $x } $ bash testme $ dash testme $ rpm -q bash dash bash-4.2.53-2.fc20.i686 dash-0.5.8-1.fc20.i686
Apologies, this bug was filed prior to the proper analysis. Fedora is not affected by this flaw. Thanks for looking into this!
