Multiple security issues were discovered in LibreCAD, an application for computer aided design (CAD) which could result in denial of service or
the execution of arbitrary code if a malformed CAD file is opened.
For the oldstable distribution (buster), these problems have been fixed
in version 2.1.3-1.2+deb10u1.
For the stable distribution (bullseye), these problems have been fixed in version 2.1.3-1.3+deb11u1.
