CVE-2004-0079: 4d Webstar

High severity, CVSS 7.5. EPSS: 9.5% chance of exploitation in the next 30 days.

The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
