The IPsec module in the VPN component in Ingate Firewall before 4.6.0 and SIParator before 4.6.0 allows remote attackers to cause a denial of service (module crash) via an IPsec Phase 2 proposal that lacks Perfect Forward Secrecy (PFS).
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
