Solo son vulnerables los servidores Linux con la biblioteca glibc que utilicen OpenSSH desde la versi\u00f3n 8.5p1 hasta la 9.7p1, inclusive. El problema radica en una condici\u00f3n de carrera en los manejadores de se\u00f1ales.<\/p>\n<p>El ataque ha sido demostrado hasta ahora solo en condiciones de laboratorio en sistemas de 32 bits y toma alrededor de 6 a 8 horas. Los sistemas de 64 bits te\u00f3ricamente tambi\u00e9n son vulnerables, pero debido a un espacio de direcciones mucho mayor utilizado para ASLR, la explotaci\u00f3n a\u00fan no ha sido posible.<\/p>\n<p>Los sistemas con otras implementaciones de libc tambi\u00e9n pueden ser susceptibles a la vulnerabilidad.
