Descriptions
GNU C Library (aka glibc) before 2.20 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via a multibyte character value of "0xffff" to the iconv function when converting (1) IBM933, (2) IBM935, (3) IBM937, (4) IBM939, or (5) IBM1364 encoded data to UTF-8.
GNU C Library (también conocido como glibc) anterior a 2.20 permite a atacantes dependientes de contexto causar una denegación de servicio (lectura fuera de rango y caída) a través de un valor de caracteres de multibytes de '0xffff' en la función iconv cuando convierte datos codificados de (1) IBM933, (2) IBM935, (3) IBM937, (4) IBM939, o (5) IBM1364 a UTF-8.
An out-of-bounds read flaw was found in the way glibc's iconv() function converted certain encoded data to UTF-8. An attacker able to make an application call the iconv() function with a specially crafted argument could use this flaw to crash that application.
