CVE-2017-9022 (opens in a new tab)How to fix?
Upgrade Alpine:3.14 strongswan to version 5.5.3-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream strongswan package and not the strongswan package as distributed by Alpine.
See How to fix? for Alpine:3.14 relevant fixed versions and status.
The gmp plugin in strongSwan before 5.5.3 does not properly validate RSA public keys before calling mpz_powm_sec, which allows remote peers to cause a denial of service (floating point exception and process crash) via a crafted certificate.
