A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients.
CVE-2016-8610
Score elevated to 7.8 because EPSS predicts 40% probability of exploitation within the next 30 days (top 1.5% of all CVEs). NVD baseline CVSS 7.5 retained for reference. Confidence: see factors.
