Debian Security Advisory                             security@debian.org

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
