ResolverFuzz: Automated Discovery of DNS Resolver Vulnerabilities with Query-Response Fuzzing. (arXiv:2310.03202v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Domain Name System (DNS) is a critical component of the Internet. DNS
resolvers, which act as the cache between DNS clients and DNS nameservers, are
the central piece of the DNS infrastructure, essential to the scalability of
DNS. However, finding the resolver vulnerabilities is non-trivial, and this
problem is not well addressed by the existing tools. To list a few reasons,
first, most of the known resolver vulnerabilities are non-crash bugs that
cannot be directly detected by the existing oracles …
