CVE-2004-0079
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.

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.54%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
