Alpine: libcrypto3, multiple openssl packages: security update to 1.1.1-r1 (deprecated)

medium Tenable Self-Hosted Container Security Plugin ID 400516

Description

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

 - Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant
 code paths. However, in some cases, it is possible to construct a group using explicit parameters (instead
 of using a named curve). In those cases it is possible that such a group does not have the cofactor
 present. This can occur even where all the parameters match a known named curve. If such a curve is used
 then OpenSSL falls back to non-side channel resistant code paths which may result in full key recovery
 during an ECDSA signature operation. In order to be vulnerable an attacker would have to have the ability
 to time the creation of a large number of signatures where explicit parameters with no co-factor present
 are in use by an application using libcrypto. For the avoidance of doubt libssl is not vulnerable because
 explicit parameters are never used. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL
 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s). (CVE-2019-1547)

 - OpenSSL 1.1.1 introduced a rewritten random number generator (RNG). This was intended to include
 protection in the event of a fork() system call in order to ensure that the parent and child processes did
 not share the same RNG state. However this protection was not being used in the default case. A partial
 mitigation for this issue is that the output from a high precision timer is mixed into the RNG state so
 the likelihood of a parent and child process sharing state is significantly reduced. If an application
 already calls OPENSSL_init_crypto() explicitly using OPENSSL_INIT_ATFORK then this problem does not occur
 at all. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). (CVE-2019-1549)

 - In situations where an attacker receives automated notification of the success or failure of a decryption
 attempt an attacker, after sending a very large number of messages to be decrypted, can recover a
 CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the
 public RSA key, using a Bleichenbacher padding oracle attack. Applications are not affected if they use a
 certificate together with the private RSA key to the CMS_decrypt or PKCS7_decrypt functions to select the
 correct recipient info to decrypt. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL
 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s). (CVE-2019-1563)
