Dropbear is an SSH server and client with a small memory
|
|
footprint.

<description>
|
|
<p>
|
|
Under certain conditions Dropbear could fail to allocate a
|
|
sufficient amount of memory, possibly resulting in a buffer overflow.

|
<impact type="high">
|
|
<p>
|
|
By sending specially crafted data to the server, authenticated
|
|
users could exploit this vulnerability to execute arbitrary code with
|
|
the permissions of the SSH server user, which is the root user by
|
|
default.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

<resolution>
|
|
<p>
|

All Dropbear users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/dropbear-0.47"</code>
