Unspecified vulnerability in Ingate Firewall before 4.6.0 and SIParator before 4.6.0 might leave "media pinholes" open upon a restart of the SIP module, which might make it easier for remote attackers to conduct unauthorized activities.

Ingate Firewall before 4.3.4 and SIParator before 4.3.4 allows remote attackers to cause a denial of service (kernel deadlock) by sending a SYN packet for a TCP stream, which requires an RST packet in response.

Cross-site scripting (XSS) vulnerability in the web interface in Ingate Firewall before 4.4.1 and SIParator before 4.4.1 allows remote attackers to inject arbitrary web script or HTML, and steal cookies, via unspecified vectors related to "XSS exploits" in administrator functionality.

The SIP module in Ingate Firewall before 4.6.1 and SIParator before 4.6.1 does not reuse SIP media ports in unspecified call hold and send-only stream scenarios, which allows remote attackers to cause a denial of service (port exhaustion) via unspecified vectors.
