A vulnerability was discovered in libnids, a library used to analyze
IP network traffic, whereby a carefully crafted TCP datagram could
cause memory corruption and potentially execute arbitrary code with
the privileges of the user executing a program which uses libnids
(such as dsniff).
For the current stable distribution (woody) this problem has been
fixed in version 1.16-3woody1.
For the unstable distribution (sid) this problem will be fixed soon.
We recommend that you update your libnids package.
