If a vulnerable version of tcpdump attempted to examine a maliciously constructed packet, a number of buffer overflows could be exploited to crash tcpdump, or potentially execute arbitrary code with the privileges of the tcpdump process. CAN-2003-1029 - infinite loop and memory consumption in processing L2TP packets CAN-2003-0989, CAN-2004-0057 - infinite loops in processing ISAKMP packets. CAN-2004-0055 - segmentation fault caused by a RADIUS attribute with a large length value For the current stable distribution (woody) these problems have been fixed in version 3.6.2-2.7. For the unstable distribution (sid) these problems will be fixed soon. We recommend that you update your tcpdump package. Upgrade Instructions - - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
