An attacker is able to send a specially crafted network packet which causes tcpdump to enter an infinite loop. In addition to the above problem the tcpdump developers discovered a potential infinite loop when parsing malformed BGP packets. They also discovered a buffer overflow that can be exploited with certain malformed NFS packets. For the stable distribution (woody) these problems have been fixed in version 3.6.2-2.3. For the old stable distribution (potato) does not seem to be affected by this problem. For the unstable distribution (sid) these problems have been fixed in version 3.7.1-1.2. We recommend that you upgrade your tcpdump packages. 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.
