USN-3397-1: strongSwan vulnerability

21 August 2017

strongSwan could be made to crash or hang if it received specially crafted network traffic.




It was discovered that strongSwan incorrectly handled verifying
specific RSA signatures. A remote attacker could use this issue
to cause strongSwan to crash, resulting in a denial of service.
