libcharon in strongSwan 5.9.7 through 6.0.7 mishandles behavioral workflow in the IKEv2 state machine. Because CREATE_CHILD_SA requests are mishandled, there can be an authentication bypass.
strongSwan 4.5.0 through 6.0.7 has Incorrect Access Control in the eap-ttls and eap-peap plugins because there can be a missing or mismatched inner EAP identity.
strongSwan 5.1.3 through 6.0.7 has an infinite loop in the x509 plugin's attribute certificate parser for ietfAttrSyntax.
strongSwan 4.2.0 through 6.0.7 has a missing release of memory after its effective lifetime in the x509 plugin's attribute certificate parser.
strongSwan 4.2.0 through 6.0.7 has a NULL pointer dereference in the x509 plugin's attribute certificate parser.
strongSwan 4.6.2 through 6.0.7 has an infinite loop in PKCS#5 decryption.
libcharon in strongSwan 4.1.2 through 6.0.7 has a missing release of memory after its effective lifetime in the IKE message parser.
strongSwan 4.1.10 through 6.0.7 allows a NULL pointer dereference in the eap-aka plugin.
strongSwan 5.0.2 through 6.0.7 allows PKCS#7 certificate enumeration in the openssl plugin that leads to a lack of release of memory after its effective lifetime.
strongSwan 5.0.2 through 6.0.7 has an Expired Pointer Dereference in PKCS#7 parsing in the openssl plugin.
In strongSwan before 6.0.7, identity parsing/cloning is mishandled. Parsed EAP-Identities that result in an empty but non-NULL encoding are not correctly cloned and trigger a double-free once the duplicates are destroyed.
Possible NULL-Pointer Dereference in RSA Decryption
Integer Underflow When Handling RADIUS Attributes
NULL-Pointer Dereference When Handling ECDH Public Value in TLS
Accepting Certificates Violating Name Constraints
Integer Underflow When Handling EAP-SIM/AKA Attributes
NULL-Pointer Dereference When Processing Padding in PKCS#7
Infinite Loop When Handling Supported Versions TLS Extension
strongSwan versions 4.5.0 prior to 6.0.5 contain an integer underflow vulnerability in the EAP-TTLS AVP parser that allows unauthenticated remote attackers to cause a denial of service by sending crafted AVP data with invalid length fields during IKEv2 authentication. Attackers can exploit the failure to validate AVP length fields before subtraction to trigger excessive memory allocation or NULL pointer dereference, crashing the charon IKE daemon.
In the eap-mschapv2 plugin (client-side) in strongSwan before 6.0.3, a malicious EAP-MSCHAPv2 server can send a crafted message of size 6 through 8, and cause an integer underflow that potentially results in a heap-based buffer overflow.
