<impact type="normal">
|
|
|
|
|
<p>A remote attacker could possibly execute arbitrary code with the
|
|
|
|
|
privileges of the process, or cause a Denial of Service condition.
|
|
|

|
|
<workaround>
|
|
|
|
|
<p>There is no known workaround at this time. However, on Gentoo, the
|
|
|
|
|
remote code execution vulnerability can be avoided if you don’t use
|
|
|
|
|
BusyBox’s udhcpc or build the package without the “ipv6” USE flag
|
|
|
|
|
enabled.
|
|
|

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