Alpine: openssl3: security update to 3.0.2-r0

high Tenable Self-Hosted Container Security Plugin ID 406165

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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)

 - The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop
 forever for non-prime moduli. Internally this function is used when parsing certificates that contain
 elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point
 encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has
 invalid explicit curve parameters. Since certificate parsing happens prior to verification of the
 certificate signature, any process that parses an externally supplied certificate may thus be subject to a
 denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they
 can contain explicit elliptic curve parameters. Thus vulnerable situations include: - TLS clients
 consuming server certificates - TLS servers consuming client certificates - Hosting providers taking
 certificates or private keys from customers - Certificate authorities parsing certification requests from
 subscribers - Anything else which parses ASN.1 elliptic curve parameters Also any other applications that
 use the BN_mod_sqrt() where the attacker can control the parameter values are vulnerable to this DoS
 issue. In the OpenSSL 1.0.2 version the public key is not parsed during initial parsing of the certificate
 which makes it slightly harder to trigger the infinite loop. However any operation which requires the
 public key from the certificate will trigger the infinite loop. In particular the attacker can use a self-
 signed certificate to trigger the loop during verification of the certificate signature. This issue
 affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. It was addressed in the releases of 1.1.1n and 3.0.2 on the
 15th March 2022. Fixed in OpenSSL 3.0.2 (Affected 3.0.0,3.0.1). Fixed in OpenSSL 1.1.1n (Affected
 1.1.1-1.1.1m). Fixed in OpenSSL 1.0.2zd (Affected 1.0.2-1.0.2zc). (CVE-2022-0778)
