Debian: New tcpdump packages fix denial of service
Summary
- --------------------------------------------------------------------------Debian Security Advisory DSA 854-1 security@debian.org http://www.debian.org/security/ Martin Schulze October 9th, 2005 http://www.debian.org/security/faq - --------------------------------------------------------------------------Package : tcpdump Vulnerability : infinite loop Problem type : remote Debian-specific: no CVE ID : CAN-2005-1267 Simon Nielsen discovered that the BGP dissector in tcpdump, a powerful tool for network monitoring and data acquisition, does not properly handle a -1 return value from an internal function that decodes data packets. A specially crafted BGP packet can cause a denial of service via an infinite loop. The old stable distribution (woody) is not affected by this problem. For the stable distribution (sarge) this problem has been fixed in version 3.8.3-5sarge1. We recommend that you upgrade 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.
