<title>mtink: Insecure tempfile handling</title>
|
||
|
|
<synopsis>
|
||
|
|
mtink is vulnerable to symlink attacks, potentially allowing a local user
|
||
|
|
to overwrite arbitrary files with the rights of the user running the
|
||
|
|
utility.

<p>
|
||
|
|
Tavis Ormandy from Gentoo Linux discovered that mtink uses insecure
|
||
|
|
permissions on temporary files.

<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
|
||
|
|
mtink 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.
|
||
|
|
</p>
|
||
|

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

<p>

|

All mtink users should upgrade to the latest version:
|

# emerge --sync

# emerge --ask --oneshot --verbose ">=net-print/mtink-1.0.5"</code>
