The cdrtools package is a set of tools for CD recording, including the
|
|
popular cdrecord command-line utility.

Max Vozeler discovered that the cdrecord utility, when set to SUID root,
|
|
fails to drop root privileges before executing a user-supplied RSH program.
|
|
By default, Gentoo does not ship the cdrecord utility as SUID root and
|
|
therefore is not vulnerable. However, many users (and CD-burning
|
|
front-ends) set this manually after installation.

<impact type="high">
|
|
<p>
|
|
A local attacker could specify a malicious program using the $RSH
|
|
environment variable and have it executed by the SUID cdrecord, resulting
|
|
in root privileges escalation.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
As a workaround, you could remove the SUID rights from your cdrecord
|
|
utility :
|
|
</p>
|
|
<code>
|
|
# chmod a-s /usr/bin/cdrecord</code>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All cdrtools users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=app-cdr/cdrtools-2.01_alpha37-r1"
|
|
# emerge ">=app-cdr/cdrtools-2.01_alpha37-r1"</code>
|
|
</resolution>
