Synopsis: Moderate: tcpdump security and bug fix update
Issue date: 2007-11-15
CVE Names: CVE-2007-1218 CVE-2007-3798
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.
