Descriptions

Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in the GNU C Library (aka glibc or libc6) allows remote attackers to cause a denial of service (crash) via vectors involving hostent conversion. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-4458.

Desbordamiento del buffer basado en pila en la función getaddrinfo en sysdeps/posix/getaddrinfo.c en GNU C Library (también conocida como glibc o libc6) permite a atacantes remotos provocar una denegación de servicio (caída) a través de vectores relacionados con la conversión hostent. NOTA: esta vulnerabilidad existe debido a una reparación incompleta de CVE-2013-4458.

It was discovered that the GNU C Library incorrectly handled the strxfrm function. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code.
