[RHSA-2003:174-01] Updated tcpdump packages fix privilege dropping error From: bugzilla@redhat.com To: redhat-watch-list@redhat.com Date: Thursday 10.03.00 --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated tcpdump packages fix privilege dropping error Advisory ID: RHSA-2003:174-01 Issue date: 2003-05-15 Updated on: 2003-05-15 Product: Red Hat Linux Keywords: tcpdump Cross references: Obsoletes: RHSA-2003:032- CVE Names: CAN-2003-0194 --------------------------------------------------------------------- 1. Topic: Updated tcpdump packages that correctly drop privileges on startup are now available. 2. Relevant releases/architectures: Red Hat Linux 7.1 - i386 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 Red Hat Linux 9 - i386 3. Problem description: Tcpdump is a command-line tool for monitoring network traffic. The Red Hat tcpdump packages advertise that by default tcpdump will drop permissions to user 'pcap'. Due to a compilation error this did not happen, and tcpdump would run as root unless the '-U' flag was specified. Users of tcpdump are advised to upgrade to these errata packages, which contain are compiled so that by default tcpdump will drop privileges to the 'pcap' user. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 88881 - CAN-2003-0145 RADUIS tcpdump vulnerability 90208 - CAN-2003-0194 tcpdump didn't drop root to pcap user like promised 6.
