Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions TCPreen versions prior to 1.4.4

Description The issue is related to multiple stack-based buffer overflows in the use of FD SET, allowing remote attackers to cause a denial of service via multiple concurrent connections. This results in overflows in the SocketAddress::Connect function in libsolve/sockprot.cpp and the monitor bridge function in src/bridge.cpp.

Recommendations For versions prior to 1.4.4, update to version 1.4.4 or later to resolve the issue. As a temporary workaround, consider restricting the number of concurrent connections to minimize the risk of exploitation.
