HIGH

xscreensaver - Improper Privilege Management via cap_net_raw Capability

Title source: llm
STIX 2.1

Description

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.
