Summary

In openFPGALoader version 1.1.1 and earlier, a heap-buffer-overflow read vulnerability exists in BitParser::parseHeader() that allows out-of-bounds heap memory access when parsing a crafted .bit file. No FPGA hardware is required to trigger this vulnerability.

Risk Assessment

The risk involves potential remote reading of sensitive data from process memory or causing a denial of service (DoS) by delivering a malicious .bit file. The attack does not require physical access to FPGA hardware, increasing the attack surface.

Recommendation

Immediately update openFPGALoader to a version newer than 1.1.1 once a patch is released. Until then, avoid opening .bit files from untrusted sources.
