CVE-2011-4619
The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service (CPU consumption) via unspecified vectors.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 17.8%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
