The remote host is missing updates announced in advisory CLA-2004:801.
Ethereal[1] is a powerful network traffic analyzer with a graphical user interface (GUI).
This update announcement addresses vulnerabilities[2] in the SMB (CVE-2003-1012[3]) and Q.931 (CVE-2003-1013[4]) protocol dissectors.
These vulnerabilities can be exploited by an attacker who can insert crafted packets in the wire being monitored by ethereal or make an user open a trace file with such packets inside. When reading this data, Ethereal will crash. The possibility of execution of arbitrary code has not been investigated.
Solution: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade'
