libpcap and tcpdump downloads could contain a backdoor

libpcap-tcpdump-backdoor (10620) The risk level is classified as HighHigh Risk

Description:

The libpcap and tcpdump tools, if downloaded from (www.tcpdump.org) or libpcap and tcpdump mirrored FTP sites between 11-Nov-2002 and 13-Nov-2002, could cause a backdoor to be installed on victim's computers. One of the Web site's hosting these tools (www.tcpdump.org) was compromised on or before 11-Nov-2002 and the libpcap-0.7.1.tar.gz, tcpdump-3.6.2.tar.gz, and tcpdump-3.7.1.tar.gz files were modified to include a Trojan Horse. This could allow a remote attacker to gain access to systems that have installed the compromised libpcap and tcpdump distributions and execute commands on the system with privileges of the user who installed the affected packages.


Consequences:

Gain Access

Remedy:

Users should verify that they have an authentic version of libpcap or tcpdump installed. Refer to CERT Advisory CA-2002-30 for more information. See References.
