Alpine: strongswan: security update to 5.8.4-r3

high Tenable Cloud Security Plugin ID 407257

Description

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

 - The gmp plugin in strongSwan before 5.9.4 has a remote integer overflow via a crafted certificate with an
 RSASSA-PSS signature. For example, this can be triggered by an unrelated self-signed CA certificate sent
 by an initiator. Remote code execution cannot occur. (CVE-2021-41990)

 - The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving
 many requests with different certificates to fill the cache and later trigger the replacement of cache
 entries. The code attempts to select a less-often-used cache entry by means of a random number generator,
 but this is not done correctly. Remote code execution might be a slight possibility. (CVE-2021-41991)
