Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-10-31 14:16:52 UTC 
CVE-2022-40617:

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.

Please remember to file security bugs for your packages! Please
stabilize when erady.
