RumFuzz: Coverage-guided Greybox Fuzzing with Reasonable Use of Memory

2024

Coverage-guided Greybox Fuzzing (CGF) is one of the most popular vulnerability detection methods. AFL-based fuzzers typically use a fixed-size 64KB bitmap to record edge coverage information. However, for small programs, 64KB is larger than their …

Reason2Attack: Jailbreaking Text-to-Image Models via LLM Reasoning
