Xelerance: >> Openswan >> 2.3.0 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 2.6.39 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon restart) via IKEv2 packets that lack expected payloads.

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.

Use-after-free vulnerability in the cryptographic helper handler functionality in Openswan 2.3.0 through 2.6.36 allows remote authenticated users to cause a denial of service (pluto IKE daemon crash) via vectors related to the (1) quick_outI1_continue and (2) quick_outI1 functions.

Stack-based buffer overflow in the get_internal_addresses function in the pluto application for Openswan 1.x before 1.0.9, and Openswan 2.x before 2.3.0, when compiled with XAUTH and PAM enabled, allows remote authenticated attackers to execute arbitrary code.
