As a result, a malicious user that has access to a jailed system is able to abuse shared memory by injecting malicious content in the shared memory region. This memory region might be executed by applications trusting the shared memory, like Squid. This issue could lead to a Denial of Service or local privilege escalation."}, {"lang": "es", "value": "En FreeBSD en versiones 10.x anteriores a 10.4-STABLE, 10.4-RELEASE-p3 y 10.3-RELEASE-p24, las rutas nombradas tienen alcance global, lo que significa que un proceso localizado en una jaula puede leer y modificar el contenido de los objetos de la memoria compartida de POSIX creados por un proceso en otra jaula o el sistema host. Como resultado, un usuario malicioso que tenga acceso al sistema enjaulado puede vulnerar la memoria compartida inyectando contenidos maliciosos en la regi\u00f3n de memoria compartida. Esta regi\u00f3n de memoria podr\u00eda ser ejecutada por aplicaciones que conf\u00eden en la memoria compartida, como Squid.
