Multiple out-of-bounds write vulnerabilities exist in the VCD parse_valuechange portdump functionality of GTKWave 3.3.115. A specially crafted .vcd file can lead to arbitrary code execution. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns the out-of-bounds write when triggered via the GUI’s legacy VCD parsing code.
