It was discovered that several buffer overflows in tcpreen, a tool for
monitoring a TCP connection, may lead to denial of service.
The old stable distribution (sarge) doesn’t contain tcpreen.
For the stable distribution (etch), this problem has been fixed in
version 1.4.3-0.1etch1.
For the unstable distribution (sid), this problem has been fixed in
version 1.4.3-0.3.
We recommend that you upgrade your tcpreen package.
