<p>Two vulnerabilities have been found in Bash:</p>
|
|
|
|
<ul>
|
|
<li>Bash example scripts do not handle temporary files securely
|
|
(CVE-2008-5374).
|
|
</li>
|
|
<li>Improper bounds checking in Bash could cause a stack-based buffer
|
|
overflow (CVE-2012-3410).
|
|
</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>A remote attacker could entice a user to open a specially crafted Bash
|
|
script, possibly resulting in execution of arbitrary code with the
|
|
privileges of the process, or a Denial of Service condition of the Bash
|
|
executable.
|
|
</p>
|
|
|
|
<p>A local attacker may be able to perform symlink attacks to overwrite
|
|
arbitrary files with the privileges of the user running the application
|
|
or bypass shell access restrictions.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All Bash users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-shells/bash-4.2_p37"
|
|
</code>
