The OpenSSL project reports:

High: CA certificate check bypass with X509_V_FLAG_X509_STRICT
(CVE-2021-3450)The X509_V_FLAG_X509_STRICT flag enables
additional security checks of the certificates present in a
certificate chain. It is not set by default.
High: NULL pointer deref in signature_algorithms processing
(CVE-2021-3449)An OpenSSL TLS server may crash if sent a
maliciously crafted renegotiation ClientHello message from a client.
If a TLSv1.2 renegotiation ClientHello omits the
signature_algorithms extension (where it was present in the initial
ClientHello), but includes a signature_algorithms_cert extension
then a NULL pointer dereference will result, leading to a crash and
a denial of service attack.
