CVE-2013-4466: n/a vulnerability

CVE-2013-4466: Buffer overflow in the dane_query_tlsa function in the DANE library (libdane) in GnuTLS 3.1.x before 3.1.15...

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.

Security readout for executives and security teams

Older GnuTLS libdane versions can crash or corrupt memory when a remote server returns too many DANE entries. This is mainly a business risk for legacy systems that still use affected GnuTLS DANE/TLSA functionality. The known impact in the source bundle is denial of service, not confirmed data theft or active exploitation. Exposure is most likely on legacy hosts, appliances, or applications linked against GnuTLS libdane 3.1.x or 3.2.x and using DANE/TLSA lookups. Modern supported GnuTLS deployments are unlikely to be affected if they include the 2013 fixes or vendor backports. Treat this as a targeted legacy dependency cleanup item. It is not marked as actively exploited, but affected systems can be remotely crashed when using vulnerable DANE functionality. Prioritize confirmation and upgrades where GnuTLS libdane is in production paths. Mitigation focus: Inventory systems and applications using GnuTLS libdane.; Upgrade GnuTLS 3.1.x to 3.1.15 or later.; Upgrade GnuTLS 3.2.x to 3.2.5 or later..
