CVE-2017-1000376

https://notcve.org/view.php?id=CVE-2017-1000376

libffi requests an executable stack allowing attackers to more easily trigger arbitrary code execution by overwriting the stack. Please note that libffi is used by a number of other libraries. It was previously stated that this affects libffi version 3.2.1 but this appears to be incorrect. libffi prior to version 3.1 on 32 bit x86 systems was vulnerable, and upstream is believed to have fixed this issue in version 3.1. libffi solicita una pila ejecutable que permite que los atacantes desencadenen con más facilidad la ejecución de código arbitrario sobrescribiendo la pila. Se debe tener en cuenta que libffi es empleado por otras bibliotecas. Antes se dijo que esto afecta a la versión 3.2.1 de libffi, pero parece ser incorrecto. libffi en versiones anteriores a la 3.1 en sistemas x86 de 32 bits era vulnerable y se cree que upstream ha solucionado este problema en la versión 3.1. • http://www.debian.org/security/2017/dsa-3889 https://access.redhat.com/security/cve/CVE-2017-1000376 https://www.oracle.com/security-alerts/cpujan2020.html https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
