The Debian security team deemed this advisory irrelevant for Debian:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream xscreensaver package and not the xscreensaver package as distributed by Debian.
The Debian xscreensaver 5.42+dfsg1-1 package for XScreenSaver has cap_net_raw enabled for the /usr/libexec/xscreensaver/sonar file, which allows local users to gain privileges because this is arguably incompatible with the design of the Mesa 3D Graphics library dependency.
