<description>
|
|
<p>
|
|
BEAST, which is installed as setuid root, fails to properly check
|
|
whether it can drop privileges accordingly if seteuid() fails due to a
|
|
user exceeding assigned resource limits.
|
|
</p>
|
|
</description>
|
|
<impact type="low">
|
|
<p>
|
|
A local user could exceed his resource limit in order to prevent the
|
|
seteuid() call from succeeding. This may lead BEAST to keep running
|
|
with root privileges. Then, the local user could use the "save as"
|
|
dialog box to overwrite any file on the vulnerable system, potentially
|
|
leading to a Denial of Service.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All BEAST users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-sound/beast-0.7.1"</code>
|
|
