|
When the mailbox is created in useradd, the "open()" function does
|
|
not receive the three arguments it expects while O_CREAT is present,
|
|
which leads to random permissions on the created file, before fchmod()
|
|
is executed.
|
|
</p>

|
|
<impact type="normal">
|
|
<p>
|
|
Depending on the random permissions given to the mailbox file
|
|
which is at this time owned by root, a local user may be able to open
|
|
this file for reading or writing, or even executing it, maybe as the
|
|
root user.
|
|
</p>
|

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All shadow users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-apps/shadow-4.0.15-r2"</code>
