Description Andrej Nemec 2017-01-19 09:05:15 UTC

php-gettext code that parses the plural forms header relies on eval() and only filters out some known-bad characters before passing the value from a MO file in directly to eval().

Is there any patch available already? The NagVis fork seems to just rip out 
the functionality rather really fixing the issue...

There is no upstream patch available yet as far as I was able to find out.
