CVE-2015-1794
The ssl3_get_key_exchange function in ssl/s3_clnt.c in OpenSSL 1.0.2 before 1.0.2e allows remote servers to cause a denial of service (segmentation fault) via a zero p value in an anonymous Diffie-Hellman (DH) ServerKeyExchange message.

Does this matter?
Lower severity and a low EPSS score (4.98%). Track it; it rarely justifies an emergency change on its own.
