Severity
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H
Summary
openFPGALoader is a utility for programming FPGAs. In 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.
