Descriptions

Off-by-one error in the __gconv_translit_find function in gconv_trans.c in GNU C Library (aka glibc) allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via vectors related to the CHARSET environment variable and gconv transliteration modules.

Error de superación de límite (off-by-one) en la función __gconv_translit_find en gconv_trans.c en GNU C Library (también conocido como glibc) permite a atacantes dependientes de contexto causar una denegación de servicio (caída) o ejecutar código arbitrario a través de vectores relacionados con la variable del entorno CHARSET y los módulos de transliteración gconv.

An off-by-one heap-based buffer overflow flaw was found in glibc's internal __gconv_translit_find() function. An attacker able to make an application call the iconv_open() function with a specially crafted argument could possibly use this flaw to execute arbitrary code with the privileges of that application.
