The ASN.1 parser (pluto/asn1.c, libstrongswan/asn1/asn1.c, libstrongswan/asn1/asn1_parser.c) in (a) strongSwan 2.8 before 2.8.10, 4.2 before 4.2.16, and 4.3 before 4.3.2; and (b) openSwan 2.6 before 2.6.22 and 2.4 before 2.4.15 allows remote attackers to cause a denial of service (pluto IKE daemon crash) via an X.509 certificate with (1) crafted Relative Distinguished Names (RDNs), (2) a crafted UTCTIME string, or (3) a crafted GENERALIZEDTIME string.

Security readout for executives and security teams

This issue lets a remote attacker crash the VPN IKE service by presenting a malformed X.509 certificate. The documented impact is denial of service, not data theft or code execution. Business urgency is highest for internet-facing IPsec VPN gateways running affected strongSwan or openSwan versions. Exposure is likely limited to systems using affected strongSwan or openSwan IPsec/IKE services with X.509 certificate handling enabled. Internet-facing VPN concentrators and security appliances using vulnerable downstream packages should be prioritized. Treat as a service availability risk for VPN access. Patch exposed VPN infrastructure promptly, especially systems supporting remote workforce, site-to-site connectivity, or customer access. Mitigation focus: Upgrade strongSwan to 2.8.10, 4.2.16, 4.3.2, or later as applicable.; Upgrade openSwan to 2.4.15, 2.6.22, or later as applicable.; Check OS and appliance vendor advisories for backported package fixes..
