The compare_dn function in utils/identification.c in strongSwan 4.3.3 through 5.1.1 allows (1) remote attackers to cause a denial of service (out-of-bounds read, NULL pointer dereference, and daemon crash) or (2) remote authenticated users to impersonate arbitrary users and bypass access restrictions via a crafted ID_DER_ASN1_DN ID, related to an "insufficient length check" during identity comparison.

Security readout for executives and security teams

This flaw affects strongSwan VPN software versions 4.3.3 through 5.1.1. A crafted identity value can crash the VPN daemon, causing service disruption. In authenticated scenarios, it may also let a user impersonate another identity and bypass access restrictions. Most exposure is on systems running affected strongSwan versions for IPsec/VPN services, especially internet-facing or partner-facing gateways. The source bundle does not identify affected downstream package versions beyond strongSwan and Debian advisory references. Treat as high priority for affected VPN infrastructure because it can disrupt remote access and may weaken identity-based restrictions. Focus first on externally reachable strongSwan gateways and environments where VPN identity maps to authorization. Mitigation focus: Inventory strongSwan deployments and confirm whether versions 4.3.3 through 5.1.1 are present.; Apply the strongSwan security patch or vendor-supported fixed package referenced by project or distribution guidance.; Review Debian advisory guidance where Debian-packaged strongSwan is used..
