strongSwan 4.3.3-5.1.1 - Denial of Service and Authentication Bypass via Crafted ID_DER_ASN1_DN ID
Title source: llmDescription
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.
