Scientific Linux Security Update : tcpdump on SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

Problem description :

Moritz Jodeit discovered a denial of service bug in the tcpdump IEEE
802.11 processing code. If a certain link type was explicitly
specified, an attacker could inject a carefully crafted frame onto the
IEEE 802.11 network that could crash a running tcpdump session.
(CVE-2007-1218)

An integer overflow flaw was found in tcpdump's BGP processing code.
An attacker could execute arbitrary code with the privilege of the
pcap user by injecting a crafted frame onto the network.
(CVE-2007-3798)

In addition, the following bugs have been addressed :

- The arpwatch service initialization script would exit
prematurely, returning an incorrect successful exit
status and preventing the status command from running in
case networking is not available.

- Tcpdump would not drop root privileges completely when
launched with the

- -C option. This might have been abused by an attacker to
gain root privileges in case a security problem was
found in tcpdump. Users of tcpdump are encouraged to
specify meaningful arguments to the -Z option in case
they want tcpdump to write files with privileges other
than of the pcap user.

Solution :

Update the affected arpwatch, libpcap and / or tcpdump packages.

Risk factor :

Medium / CVSS Base Score : 6.8
