Alpine: libcrypto3, multiple openssl packages: security update to 3.1.4-r4

medium Tenable Cloud Security Plugin ID 424358

Description

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

 - Issue summary: Checking excessively long invalid RSA public keys may take a long time. Impact summary:
 Applications that use the function EVP_PKEY_public_check() to check RSA public keys may experience long
 delays. Where the key that is being checked has been obtained from an untrusted source this may lead to a
 Denial of Service. When function EVP_PKEY_public_check() is called on RSA public keys, a computation is
 done to confirm that the RSA modulus, n, is composite. For valid RSA keys, n is a product of two or more
 large primes and this computation completes quickly. However, if n is an overly large prime, then this
 computation would take a long time. An application that calls EVP_PKEY_public_check() and supplies an RSA
 key obtained from an untrusted source could be vulnerable to a Denial of Service attack. The function
 EVP_PKEY_public_check() is not called from other OpenSSL functions however it is called from the OpenSSL
 pkey command line application. For that reason that application is also vulnerable if used with the
 '-pubin' and '-check' options on untrusted data. The OpenSSL SSL/TLS implementation is not affected by
 this issue. The OpenSSL 3.0 and 3.1 FIPS providers are affected by this issue. (CVE-2023-6237)
