CVE-2007-6562: Tcpreen

Medium severity, CVSS 5.0. EPSS: 2.3% chance of exploitation in the next 30 days.

Multiple stack-based buffer overflows in the use of FD_SET in TCPreen before 1.4.4 allow remote attackers to cause a denial of service via multiple concurrent connections, which result in overflows in the (1) SocketAddress::Connect function in libsolve/sockprot.cpp and (2) monitor_bridge function in src/bridge.cpp.

Affected products

• Tcpreen Tcpreen: up to and including 1.4.3
