"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."
