Last modified

CVE-2026-110606 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. LibreCAD libdxfrw through LC2.2.0 (LibreCAD through 2.2.1.5) contains a stack-based out-of-bounds read vulnerability in dwgReader18::readFileHeader() caused by calling strlen on non-NUL-terminated buffers. Attackers can supply a crafted AC1018, AC1024 or AC1027 DWG file without NUL bytes in the decrypted header to read adjacent stack memory and crash the process.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
