Уязвимости strongswan

CVE-2026-78135

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.

CVE-2026-78134

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.

CVE-2026-78132

strongSwan 5.1.3 through 6.0.7 has an infinite loop in the x509 plugin's attribute certificate parser for ietfAttrSyntax.

CVE-2026-78131

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.

CVE-2026-78130

strongSwan 4.2.0 through 6.0.7 has a NULL pointer dereference in the x509 plugin's attribute certificate parser.

CVE-2026-78129

strongSwan 4.6.2 through 6.0.7 has an infinite loop in PKCS#5 decryption.

CVE-2026-78127

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.

CVE-2026-78126

strongSwan 4.1.10 through 6.0.7 allows a NULL pointer dereference in the eap-aka plugin.

CVE-2026-78124

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.

CVE-2026-78123

strongSwan 5.0.2 through 6.0.7 has an Expired Pointer Dereference in PKCS#7 parsing in the openssl plugin.

CVE-2026-47895

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.

strongSwan 4.5.0 < 6.0.5 EAP-TTLS AVP Parsing Integer Underflow

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.
