<p>
|
|
Ervin Nemeth discovered that mirrorselect creates temporary files in
|
|
world-writable directories with predictable names.

|
<impact type="normal">
|
|
<p>
|
|
A local attacker could create symbolic links in the temporary files
|
|
directory, pointing to a valid file somewhere on the filesystem. When
|
|
mirrorselect is executed, this would result in the file being
|
|
overwritten with the rights of the user running the utility, which
|
|
could be the root user.
|
|

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</p>
|

</workaround>
|
|
<resolution>
|
|
<p>
|
|
All mirrorselect users should upgrade to the latest version:

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-portage/mirrorselect-0.89"</code>
