En el parche gssapi.patch, utilizado en muchas distribuciones de Linux, que a\u00f1ade soporte para el intercambio de claves basado en GSSAPI en OpenSSH, se ha descubierto una vulnerabilidad que provoca da\u00f1os en la memoria y el elusi\u00f3n del mecanismo de separaci\u00f3n de privilegios. Esta vulnerabilidad puede ser explotada de forma remota. Actualmente, se ha confirmado su existencia en Debian y Ubuntu. La vulnerabilidad se presenta al habilitar en la configuraci\u00f3n la opci\u00f3n «GSSAPIKeyExchange yes».<\/p>\n

Es caracter\u00edstico que, en su momento, los desarrolladores de OpenSSH se negaran a aceptar una modificaci\u00f3n para el soporte de GSSAPI debido a dudas sobre su seguridad. Sin embargo, muchas distribuciones de Linux incorporaron este parche en sus paquetes de OpenSSH.<\/p>\n
