Package : librecad
Version : 2.1.2-1+deb9u2
CVE ID : CVE-2021-21898 CVE-2021-21899 CVE-2021-21900
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.
CVE-2021-21898
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.
CVE-2021-21899
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.
CVE-2021-21900
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.
For Debian 9 stretch, these problems have been fixed in version
2.1.2-1+deb9u2.
We recommend that you upgrade your librecad packages.
