RedHat: vsftpd tcpwrappers vulnerability
Summary
Summary
In Red Hat Linux 9, the vsftpd FTP daemon switched from being run by xinetdto being run as a standalone service. In doing so, it was accidentallynot compiled against tcp_wrappers.Users of vsftpd who make use of tcp_wrappers features are advised toupgrade to these errata packages.This issue only affects Red Hat Linux 9 boxed sets manufactured fordistribution within the United States. The part numbers, which can befound on the bottom flap of the box, are RHF0120US and RHF0121US.Copies of Red Hat Linux 9 obtained through other means (such as from RedHat Network, FTP, or international boxed sets) already contain the packagesreferenced by this erratum, and are not vulnerable to this issue.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. 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.
