<description>
|
||
<p>A vulnerability was found in the way Bash expands $HOSTNAME. Injecting
|
||
malicious code into $HOSTNAME could cause it to run each time Bash
|
||
expands \h in the prompt string.

<impact type="normal">
|
||
<p>A remote attacker controlling the system’s hostname (i.e. via DHCP)
|
||
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.</p>

</workaround>
|
