When binary data are sent over a byte stream, the binary format sender and receiver are using is a "data serialization language", either explicitely specified, or implied by the implementations. Security is at risk when sender and receiver disagree on details of this language. If, e.g., the receiver fails to reject invalid messages, an adversary may assemble such invalid messages to compromise...
Despite being known since a long time, memory violations are still a very important cause of security problems in low-level programming languages containing data parsers. We address this problem by proposing a pragmatic solution to fix not only bugs, but classes of bugs. First, using a fast and safe language such as Rust, and then using a parser combinator. We discuss the advantages and difficulties...
We present a bio-inspired method for large-scale fuzzing of binary executables to detect vulnerabilities. In our approach we deploy a small group of feedback-driven explorers that guide a colony of black-box fuzzers to promising regions in input space. We achieve this by applying the biological concept of chemotaxis: The explorer fuzzers mark test case regions that drive the target binary to previously...
