This report details the creation of a syntax-aware fuzzer for PostScript interpreters (targeting Acrobat Distiller and PSNormalizer). It covers building a comprehensive PostScript grammar in ANTLR, randomly walking parser rules to construct parse trees with Python treelib, and traversing terminal nodes to generate test cases for discovering vulnerabilities.
