CVE-2019-19012: Oniguruma project oniguruma out-of-bounds read vulnerability
OOniguruma Project · Oniguruma

(This only affects the 32-bit compiled version). Remote attackers can cause a denial-of-service or information disclosure, or possibly have unspecified other impact, via a crafted regular expression.
