Xelerance: Security Vulnerabilities
The Libreswan Project has found a vulnerability in the processing of IKEv1 informational exchange packets which are encrypted and integrity protected using the established IKE SA encryption and integrity keys, but as a receiver, the integrity check value was not verified. This issue affects versions before 3.29.

In verify_signed_hash() in lib/liboswkeys/signatures.c in Openswan before 2.6.50.1, the RSA implementation does not verify the value of padding string during PKCS#1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used. IKEv2 signature verification is affected when RAW RSA keys are used.

Openswan 2.6.40 allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon restart) via IKEv2 packets that lack expected payloads. NOTE: this vulnerability exists because of an incomplete fix for CVE 2013-6466.

Buffer overflow in the atodn function in Openswan before 2.6.39, when Opportunistic Encryption is enabled and an RSA key is being used, allows remote attackers to cause a denial of service (pluto IKE daemon crash) and possibly execute arbitrary code via crafted DNS TXT records. NOTE: this might be the same vulnerability as CVE-2013-2052 and CVE-2013-2054.

Openswan 2.6.29 through 2.6.35 allows remote attackers to cause a denial of service (NULL pointer dereference and pluto IKE daemon crash) via an ISAKMP message with an invalid KEY_LENGTH attribute, which is not properly handled by the error handling function.

programs/pluto/xauth.c in the client in Openswan 2.6.26 through 2.6.28 allows remote authenticated gateways to execute arbitrary commands via shell metacharacters in the cisco_banner (aka server_banner) field, a different vulnerability than CVE-2010-3308.
