Descriptions

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 stack out-of-bounds read occurs in match_at() during regular expression searching. A logical error involving order of validation and access in match_at() could result in an out-of-bounds read from a stack buffer.

Un problema fue encontrado en Oniguruma versión 6.2.0, tal y como es usado en Oniguruma-mod en Ruby hasta la versión 2.4.1 y mbstring en PHP hasta la versión 7.1.5. Una lectura fuera de límites de la pila ocurre en la función match_at() durante la búsqueda de expresión regular. Un error lógico que implique el orden de validación y el acceso en match_at() podría dar lugar a una lectura fuera de límites desde un búfer de pila.
