Comment 2 Tomas Hoger 2017-09-07 12:20:56 UTC 
This bug is not triggered by a malformed phar archive, but requires a PHP script to perform specific operation on a tar-format phar archive - call to a Phar::delMetadata function.  That's rather unlikely, and does not seem to be worth calling security.
