Package        : ethereal
Problem type   : remote exploit
Debian-specific: no

hacksware reported a buffer overflow in the AFS packet parsing code in
ethereal. Gerald Combs then found more overflows in the netbios and ntp
decoding logic as well. An attacker can exploit those overflows by
sending carefully crafted packets to a network that is being monitored
by ethereal.

This has been fixed in version 0.8.0-2potato and we recommend you
upgrade your ethereal package immediately.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.
