Ingate Firewall before 4.6.0 and SIParator before 4.6.0 use cleartext storage for passwords of “administrators with less privileges,” which might allow attackers to read these passwords via unknown vectors.

The SIP component in Ingate Firewall before 4.6.0 and SIParator before 4.6.0, when Remote NAT Traversal is employed, does not properly perform user registration and message distribution, which might allow remote authenticated users to receive messages intended for other users.

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 SRTP implementation in Ingate Firewall before 4.6.0 and SIParator before 4.6.0 allows remote attackers to cause a denial of service (kernel crash) via an RTCP index that is “much more than expected.”

Buffer overflow in libsrtp in Ingate Firewall before 4.6.0 and SIParator before 4.6.0 has unknown impact and attack vectors. NOTE: it is not clear whether this issue crosses privilege boundaries.
