Descriptions

The Regular Expressions package in International Components for Unicode (ICU) for C/C++ before 2014-12-03, as used in Google Chrome before 40.0.2214.91, calculates certain values without ensuring that they can be represented in a 24-bit field, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted string, a related issue to CVE-2014-7923.

El paquete Regular Expressions en International Components para Unicode (ICU) for C/C++ en las versiones anteriores a 03-12-2014, como se utiliza en Google Chrome en versiones anteriores a 40.0.2214.91, calcula ciertos valores sin asegurarse de que pueden representarse en un campo de 24 bits, que permite a atacantes remotos causar una denegación de servicio (corrupción de memoria) o posiblemente tener otro impacto no especificado a través de una cadena manipulada, un problema relacionado con CVE-2014-7923.
