CVE-2014-9761

Múltiples desbordamientos de buffer basado en pila en la GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.23 permiten a atacantes dependientes del contexto causar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbirario a través de un argumento largo en la función (1) nan, (2) nanf o (3) nanl.

A stack overflow vulnerability was found in nan* functions that could cause applications, which process long strings with the nan function, to crash or, potentially, execute arbitrary code.

Martin Carpenter discovered that pt_chown in the GNU C Library did not properly check permissions for tty files. A local attacker could use this to gain administrative privileges or expose sensitive information. Robin Hack discovered that the Name Service Switch (NSS) implementation in the GNU C Library did not properly manage its file descriptors. An attacker could use this to cause a denial of service (infinite loop). Various other issues were also addressed.
