+ Dropbear is an SSH server and client with a small memory

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

+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-misc/dropbear-0.47"</code>
