"mrxvt, lightweight multi-tabbed X terminal emulator, allowed
(potentially remote) code execution because of improper handling of
certain escape sequences (ESC G Q).

For Debian 9 stretch, this problem has been fixed in version
0.5.4-2+deb9u1.

We recommend that you upgrade your mrxvt packages.

For the detailed security status of mrxvt please refer to its security
tracker page at: https://security-tracker.debian.org/tracker/mrxvt

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
