One of the last remaining heap-buffer-overflows without illegal input (fuzzing). Normally only encountered with in_dxf.

--- end body ---

The issue indicates a potential heap buffer overflow vulnerability in the LibreDWG library when processing certain DXF files, specifically related to the LTYPE.strings_area. This could allow an attacker to exploit the vulnerability by crafting a malicious DXF file, leading to memory corruption and potential arbitrary code execution.
