An issue that could enable rogue servers to gain user credentials from
a client in certain IKEv2 setups. (CVE-2015-4171)

A bug in decoding ID_DER_ASN1_DN ID payloads that could be used for
remote denial of service attacks. (CVE-2014-2891)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
