CVE-2013-4466: Buffer Overflow
First published: Tue Nov 19 2013(Updated: )
Buffer overflow in the dane_query_tlsa function in the DANE library (libdane) in GnuTLS 3.1.x before 3.1.15 and 3.2.x before 3.2.5 allows remote servers to cause a denial of service (memory corruption) via a response with more than four DANE entries.
