This update for strongswan provides the following fixes :
Security issues fixed :
CVE-2018-5388: Fixed a buffer underflow which may allow to a remote attacker with local user credentials to resource exhaustion and denial of service while reading from the socket (bsc#1094462).
CVE-2018-10811: Fixed a denial of service during the IKEv2 key derivation if the openssl plugin is used in FIPS mode and HMAC-MD5 is negotiated as PRF (bsc#1093536).
CVE-2018-16151,CVE-2018-16152: Fixed multiple flaws in the gmp plugin which might lead to authorization bypass (bsc#1107874).
CVE-2018-17540: Fixed an improper input validation in gmp plugin (bsc#1109845).
Other issues addressed: Fixed some client fails when the scep server URL is used with HTTPS protocol (bsc#1071853).
Reject Diffie-Hellman key exchanges using primes smaller than 1024 bit.
Handle unexpected informational message from SonicWall. (bsc#1009254)
