Please update this package in your installation as soon as possible. ___________________________________________________________________________ 1. Problem Summary Remote buffer overflows were discovered that would enable a remote attack of a local tcpdump process. Intrusion detection using tcpdump would be rendered useless since the attack stops all network activity on the system. This update also addresses the vulnerability in the decoding of AFS ACL packets, allowing a remote attacker to run arbitrary code on the local system as user root. 2. Solution Update the package from our ftp server by running the following command: rpm -Uvh ftp_path_to_filename Where ftp_path_to_filename is the following: ftp://ftp.turbolinux.com/pub/updates/6.0/security/tcpdump-3.6.2-1.i386.rpm The source RPM can be downloaded here: ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/tcpdump-3.6.2-1.src.rpm **Note: You must rebuild and install the RPM if you choose to download and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE THE SECURITY HOLE. Please verify the MD5 checksums of the updates before you install: MD5 sum Package Name ___________________________________________________________________________ c6003e7b6a614b5569ab4466950b45fd tcpdump-3.6.2-1.i386.rpm 8a471ef05ee45b9964390c1807b61ad3 tcpdump-3.6.2-1.src.rpm ___________________________________________________________________________ These packages are GPG signed by Turbolinux for security.
