Application crash via out-of-bounds decompression write
Published Mar 12, 2026 · Updated Mar 12, 2026
Heap buffer overflow in LibreDWG 0.13.3.7571 through 0.13.3.7835 allows remote attackers to crash DWG-processing applications. In decode.c, decompress_R2004_section writes one byte immediately past a heap allocation while expanding malformed R2004 section data. Exploitation requires a crafted DWG file to be processed; the demonstrated consequence is a segmentation fault and service interruption, without reported data disclosure or modification.
