Descriptions
An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 leads to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (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.
Un desbordamiento de enteros en la función search_in_range en el archivo regexec.c en Oniguruma versiones 6.x anteriores a 6.9.4_rc2, conduce a una lectura fuera de límites, en la que el desplazamiento de esta lectura está bajo el control de un atacante. (Esto solo afecta a la versión compilada de 32 bits). Los atacantes remotos pueden causar una denegación de servicio o una divulgación de información, o posiblemente tener otro impacto no especificado, por medio de una expresión regular especialmente diseñada.
An integer overflow vulnerability leading to an out-of-bounds read was found in the way Oniguruma handled regular expression quantifiers. A remote attacker could abuse this flaw by providing a malformed regular expression that, when processed by an application linked to Oniguruma, could crash the application, causing a denial of service.
