Advisory: RHSA-2003:174-04
Type: Security Advisory
Severity: N/A
Issued on: 2003-05-15
Last updated on: 2003-05-15
Affected Products: Red Hat Linux 7.1
Red Hat Linux 7.2
Red Hat Linux 7.3
Red Hat Linux 8.0
Red Hat Linux 9
CVEs (cve.mitre.org): CVE-2003-0194

Details

Updated tcpdump packages that correctly drop privileges on startup are now
available.

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.


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.
