<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>Several vulnerabilities were discovered in LibreCAD, an application
for computer aided design (CAD) in two dimensions. An attacker could
trigger code execution through malicious .dwg and .dxf files.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-21898">CVE-2021-21898</a>
<p>A code execution vulnerability exists in the
dwgCompressor::decompress18() functionality of LibreCad
libdxfrw. A specially-crafted .dwg file can lead to an
out-of-bounds write.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-21899">CVE-2021-21899</a>
<p>A code execution vulnerability exists in the
dwgCompressor::copyCompBytes21 functionality of LibreCad
libdxfrw. A specially-crafted .dwg file can lead to a heap buffer
overflow.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-21900">CVE-2021-21900</a>
<p>A code execution vulnerability exists in the dxfRW::processLType()
functionality of LibreCad libdxfrw. A specially-crafted .dxf file
can lead to a use-after-free vulnerability.</p></li>
</ul>
<p>For Debian 9 stretch, these problems have been fixed in version
2.1.2-1+deb9u2.</p>
<p>We recommend that you upgrade your librecad packages.</p>
