Analysis

Impact

The vulnerability exists in the read_2004_compressed_section function of src/decode.c in the Dwgbmp Utility of GNU LibreDWG. Executing a specially crafted DWG file can trigger an out-of-bounds read, allowing local attackers to access arbitrary memory content. The flaw is not exploitable remotely and requires local access, but a public exploit is available.

Affected Systems

GNU LibreDWG, versions up to and including 0.14.

Risk and Exploitability

The CVSS score is 4.8, indicating moderate severity. EPSS data is not available and the vulnerability is not listed in CISA KEV. Because the exploit is publicly available and local execution is required, the risk is moderate but requires timely remediation.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
