Description

CVE-2019-13224: https://nvd.nist.gov/vuln/detail/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.

A NULL Pointer Dereference in match_at() in regexec.c in Oniguruma
6.9.2 allows attackers to potentially cause denial of service by
providing a crafted regular expression. Oniguruma issues often affect
Ruby, as well as common optional libraries for PHP and Rust.
