It was discovered that OpenSSL incorrectly handled certain X.509 Email
Addresses. If a certificate authority were tricked into signing a
specially-crafted certificate, a remote attacker could possibly use this
issue to cause OpenSSL to crash, resulting in a denial of service. The
default compiler options for affected releases reduce the vulnerability to
a denial of service. (CVE-2022-3602, CVE-2022-3786)

It was discovered that OpenSSL incorrectly handled applications creating
custom ciphers via the legacy EVP_CIPHER_meth_new() function. This issue
could cause certain applications that mishandled values to the function to
possibly end up with a NULL cipher and messages in plaintext.
