<p>rssh is a restricted shell, allowing only a few commands like scp or
sftp. It is often used as a complement to OpenSSH to provide limited
access to users.
<p>Multiple command line parsing and validation vulnerabilities have been
discovered in rssh. Please review the CVE identifiers referenced below
for details.
<impact type="normal">
<p>Multiple parsing and validation vulnerabilities can cause the
restrictions set up by rssh to be bypassed.
<p>There is no known workaround at this time.</p>
<p>All rssh users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=app-shells/rssh-2.3.4"
