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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
