Alpine: openssl3: security update to 3.0.1-r0

high Tenable Self-Hosted Container Security Plugin ID 406163

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Internally libssl in OpenSSL calls X509_verify_cert() on the client side to verify a certificate supplied
 by a server. That function may return a negative return value to indicate an internal error (for example
 out of memory). Such a negative return value is mishandled by OpenSSL and will cause an IO function (such
 as SSL_connect() or SSL_do_handshake()) to not indicate success and a subsequent call to SSL_get_error()
 to return the value SSL_ERROR_WANT_RETRY_VERIFY. This return value is only supposed to be returned by
 OpenSSL if the application has previously called SSL_CTX_set_cert_verify_callback(). Since most
 applications do not do this the SSL_ERROR_WANT_RETRY_VERIFY return value from SSL_get_error() will be
 totally unexpected and applications may not behave correctly as a result. The exact behaviour will depend
 on the application but it could result in crashes, infinite loops or other similar incorrect responses.
 This issue is made more serious in combination with a separate bug in OpenSSL 3.0 that will cause
 X509_verify_cert() to indicate an internal error when processing a certificate chain. This will occur
 where a certificate does not include the Subject Alternative Name extension but where a Certificate
 Authority has enforced name constraints. This issue can occur even with valid chains. By combining the two
 issues an attacker could induce incorrect, application dependent behaviour. Fixed in OpenSSL 3.0.1
 (Affected 3.0.0). (CVE-2021-4044)
