CVE-2013-4487: n/a vulnerability

CVE-2013-4487: Off-by-one error in the dane_raw_tlsa in the DANE library (libdane) in GnuTLS 3.1.x before 3.1.16 and 3.2.x...

Off-by-one error in the dane_raw_tlsa in the DANE library (libdane) in GnuTLS 3.1.x before 3.1.16 and 3.2.x before 3.2.6 allows remote servers to cause a denial of service (memory corruption) via a response with more than four DANE entries. NOTE: this issue is due to an incomplete fix for CVE-2013-4466.

Security readout for executives and security teams

A remote server could crash software using GnuTLS libdane DANE/TLSA parsing by returning too many DANE entries. The disclosed impact is denial of service through memory corruption. Sources do not show active exploitation or code execution. Exposure is likely limited to systems using vulnerable GnuTLS/libdane versions for DANE/TLSA handling against remote servers. The provided sources do not establish exposure for general GnuTLS use without libdane DANE processing. Treat this as a targeted availability risk for services that rely on older GnuTLS libdane DANE processing. Prioritize upgrade verification on internet-facing or server-contacting applications, but do not escalate as actively exploited based on supplied evidence. Mitigation focus: Upgrade GnuTLS 3.1.x to 3.1.16 or later.; Upgrade GnuTLS 3.2.x to 3.2.6 or later.; Apply relevant distribution security updates, such as the openSUSE advisory where applicable..
