Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
smack: fix bug: unprivileged task can create labels<br />
<br />
If an unprivileged task is allowed to relabel itself<br />
(/smack/relabel-self is not empty),<br />
it can freely create new labels by writing their<br />
names into own /proc/PID/attr/smack/current<br />
<br />
This occurs because do_setattr() imports<br />
the provided label in advance,<br />
before checking "relabel-self" list.<br />
<br />
This change ensures that the "relabel-self" list<br />
is checked before importing the label.
