This flag enables additional security checks + of the certificates present in a certificate chain. It is not set by + default. + + Starting from OpenSSL version 1.1.1h a check to disallow certificates in + the chain that have explicitly encoded elliptic curve parameters was added + as an additional strict check. + + An error in the implementation of this check meant that the result of a + previous check to confirm that certificates in the chain are valid CA + certificates was overwritten. This effectively bypasses the check + that non-CA certificates must not be able to issue other certificates. + + If a "purpose" has been configured then there is a subsequent opportunity + for checks that the certificate is a valid CA. All of the named "purpose" + values implemented in libcrypto perform this check. Therefore, where + a purpose is set the certificate chain will still be rejected even when the + strict flag has been used. A purpose is set by default in libssl client and + server certificate verification routines, but it can be overridden or + removed by an application. + + In order to be affected, an application must explicitly set the + X509_V_FLAG_X509_STRICT verification flag and either not set a purpose + for the certificate verification or, in the case of TLS client or server + applications, override the default purpose. + (CVE-2021-3450) + [Tomáš Mráz] + + *) Fixed an issue where 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. + + A server is only vulnerable if it has TLSv1.2 and renegotiation enabled + (which is the default configuration). OpenSSL TLS clients are not impacted + by this issue. + (CVE-2021-3449) + [Peter Kästle and Samuel Sapalski] + Changes between 1.1.1i and 1.1.1j [16 Feb 2021] *) Fixed the X509_issuer_and_serial_hash() function.
