Descriptions

ssh in OpenSSH before 4.7 does not properly handle when an untrusted cookie cannot be created and uses a trusted X11 cookie instead, which allows attackers to violate intended policy and gain privileges by causing an X client to be treated as trusted.

ssh en OpenSSH anterior a 4.7 no maneja adecuadamente cuando una cookie no confiable no puede ser creada y utiliza una cookie X11 confiable en su lugar, lo cual permite a los atacantes violar políticas establecidas y obtener privilegios provocando que un cliente X sea tratado como confiable.
