Alpine: multiple py3-vici packages, multiple strongswan packages: security update to 5.9.1-r3

critical Tenable Cloud Security Plugin ID 424516

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)

- In strongSwan before 5.9.5, a malicious responder can send an EAP-Success message too early without
actually authenticating the client and (in the case of EAP methods with mutual authentication and EAP-only
authentication for IKEv2) even without server authentication. (CVE-2021-45079)

- strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by
sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to
a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing
after the initial TCP handshake, or sends an excessive amount of application data. (CVE-2022-40617)
