CVE-2017-11185
The gmp plugin in strongSwan before 5.6.0 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted RSA signature.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.83%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
