Descriptions

In the Linux kernel, the following vulnerability has been resolved:

fs/9p: only translate RWX permissions for plain 9P2000

Garbage in plain 9P2000's perm bits is allowed through, which causes it
to be able to set (among others) the suid bit. This was presumably not
the intent since the unix extended bits are handled explicitly and
conditionally on .u.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fs/9p: solo traduce permisos RWX para 9P2000 simple. Se permite el paso de basura en bits permanentes de 9P2000 simple, lo que hace que pueda establecer (entre otros) el bit suid. Probablemente esta no era la intención, ya que los bits extendidos de Unix se manejan explícita y condicionalmente en .u.
