Descriptions

The keycompare_mb function in sort.c in sort in GNU Coreutils through 8.23 on 64-bit platforms performs a size calculation without considering the number of bytes occupied by multibyte characters, which allows attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via long UTF-8 strings.

La función keycompare_mb en el archivo sort.c en sort en GNU Coreutils versiones hasta 8.23 ??en plataformas de 64 bits, realiza un cálculo de tamaño sin considerar el número de bytes ocupados por caracteres multibyte, lo que permite a atacantes causar una denegación de servicio (desbordamiento de búfer en la región heap de la memoria y bloqueo de aplicación) o posiblemente tener otro impacto no especificado por medio de cadenas UTF-8 largas.
