Descriptions
Buffer overflow in the gethostbyname_r and other unspecified NSS functions in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response, which triggers a call with a misaligned buffer.
Desbordamiento de buffer en gethostbyname_r y otras funciones NSS no especificadas en la librería C de GNU (también conocida como glibc o libc6) en versiones anteriores a 2.22, permite a atacantes dependientes del contexto provocar una denegación de servicio (caída) o ejecutar código arbitrario a través de una respuesta DNS manipulada, lo que desencadena una llamada con un buffer incorrectamente alineado.
A buffer overflow flaw was found in the way glibc's gethostbyname_r() and other related functions computed the size of a buffer when passed a misaligned buffer as input. An attacker able to make an application call any of these functions with a misaligned buffer could use this flaw to crash the application or, potentially, execute arbitrary code with the permissions of the user running the application.
