      "value": "An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A heap out-of-bounds write or read occurs in next_state_val() during regular expression compilation. Octal numbers larger than 0xff are not handled correctly in fetch_token() and fetch_token_in_cc(). A malformed regular expression containing an octal number in the form of '\\700' would produce an invalid code point value larger than 0xff in next_state_val(), resulting in an out-of-bounds write memory corruption."

Un vulnerabilidad de lectura o escritura fuera de l\u00edmites de la pila ocurre en la funci\u00f3n next_state_val() durante la compilaci\u00f3n de expresi\u00f3n regular. Los n\u00fameros octales mayores que 0xff no se manejan apropiadamente en fetch_token() y fetch_token_in_cc(). Una expresi\u00f3n regular malformada que contenga un n\u00famero octal en forma de \u201c\\700\u201d producir\u00eda un valor de punto de c\u00f3digo no v\u00e1lido mayor que 0xff en next_state_val(), lo que dar\u00eda como resultado una corrupci\u00f3n de memoria de escritura fuera de l\u00edmites."
