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
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
