CVE-2019-13224

A use-after-free in onignewdeluxe() 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 onignewdeluxe(). Oniguruma issues often affect Ruby, as well as common optional libraries for PHP and Rust.
