CVE-2019-13224

A use-after-free in onig_new_deluxe() in regext.c in Oniguruma 6.9.2 allows
attackers to potentially cause information disclosure, denial of service,
or possibly code execution by providing a crafted regular expression. The
attacker provides a pair of a regex pattern and a string, with a multi-byte
encoding that gets handled by onig_new_deluxe(). Oniguruma issues often
affect Ruby, as well as common optional libraries for PHP and Rust.
