CVE-2026-9500: Heap-based Buffer Overflow in GNU LibreDWG
A vulnerability was found in GNU LibreDWG up to 0.14. The affected element is the function read_2004_compressed_section of the file src/decode.c of the component Dwgread Utility. Performing a manipulation results in heap-based buffer overflow. The attack is only possible with local access. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
AI Analysis
Technical Summary
This vulnerability affects the read_2004_compressed_section function in the src/decode.c file of GNU LibreDWG up to version 0.14. It is a heap-based buffer overflow triggered by crafted input processed locally, potentially allowing an attacker with local access to cause memory corruption. The issue was responsibly reported early, but no official remediation or patch has been released as of the publication date. The CVSS 4.0 vector indicates low attack complexity and requires local privileges without user interaction.
Potential Impact
Successful exploitation can lead to heap memory corruption, which may cause application crashes or potentially enable further local privilege escalation or code execution. However, exploitation requires local access, limiting the attack surface. No confirmed exploits in the wild have been reported yet.
Mitigation Recommendations
No official patch or remediation is currently available. Users should restrict local access to trusted users only and monitor for updates from the GNU LibreDWG project. Since the vendor has not responded or issued a fix, patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
