Package        : tcpreen
Vulnerability  : buffer overflows
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-6562

It was discovered that several buffer overflows in tcpreen, a tool for
monitoring a TCP connection may lead to denial of service.

For the stable distribution (etch), this problem has been fixed in
version 1.4.3-0.1etch1.

The old stable distribution (sarge) doesn't contain tcpreen.

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.
