RedHat: Moderate: tcpdump security and bug fix update Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
RedHat Linux Updated tcpdump packages that fix a security issue and functionality bugs are now available. Moritz Jodeit discovered a denial of service bug in the tcpdump IEEE 802.11 processing code. An attacker could inject a carefully crafted frame onto the IEEE 802.11 network that could crash a running tcpdump session if a certain link type was explicitly specified. This update has been rated as having moderate security impact by the Red Hat Security Response Team.

- ---------------------------------------------------------------------

1. Summary:

Updated tcpdump packages that fix a security issue and functionality bugs
are now available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

Tcpdump is a command line tool for monitoring network traffic.

Moritz Jodeit discovered a denial of service bug in the tcpdump IEEE
802.11 processing code. An attacker could inject a carefully crafted frame
onto the IEEE 802.11 network that could crash a running tcpdump session if
a certain link type was explicitly specified. (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: 

* if called with -C and -W switches, tcpdump would create the first
savefile with the privileges of the user that executed tcpdump (usually
root), rather than with ones of the pcap user.  This could result in the
inability to save the complete traffic log file properly without the
immediate notice of the user running tcpdump.

* the arpwatch service initialization script would exit prematurely,
returning a successful exit status incorrectly and preventing the status
command from running in case networking is not available.

Users of tcpdump are advised to upgrade to these erratum packages, which
contain backported patches that correct these issues.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  

This update is available via Red Hat Network.  Details on how to use 
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bug IDs fixed (http://bugzilla.redhat.com/):

214377 - tcpdump gives 'permission denied' at 2nd file when dumping to >1 file
232519 - CVE-2007-1218 tcpdump denial of service
250275 - CVE-2007-3798 tcpdump BGP integer overflow
