Security Advisory Updated wu-ftpd packages fix remote vulnerability.

Advisory: RHSA-2003:245-15
Type: Security Advisory
Severity: N/A
Issued on: 2003-07-31
Last updated on: 2003-07-31
Affected Products: Red Hat Linux 7.1
Red Hat Linux 7.1 for iSeries
Red Hat Linux 7.1 for pSeries
Red Hat Linux 7.2
Red Hat Linux 7.3
Red Hat Linux 8.0
CVEs (cve.mitre.org): CVE-2003-0466

Details

Updated wu-ftpd packages are now available that fix a remotely exploitable
security issue.

The wu-ftpd package contains the Washington University FTP (File Transfer
Protocol) server daemon. FTP is a method of transferring files between
computers on a network.

An off-by-one bug has been discovered in versions of wu-ftpd up to and
including 2.6.2. On a vulnerable system, a remote attacker would be able
to exploit this bug to gain root privileges.

Red Hat Linux 7.1 and 7.2 contain a version of wu-ftpd that is affected by
this bug, although it is believed this issue will not be remotely
exploitable due to compiler padding of the buffer targeted for the overflow.

Red Hat Linux 7.3 and 8.0 contain a version of wu-ftpd that is remotely
exploitable.

Red Hat advises all users of wu-ftpd to upgrade to these erratum packages,
which contain a security patch and is not vulnerable to this issue.

Red Hat would like to thank Wojciech Purczynski and Janusz Niewiadomski of
ISEC Security Research for their responsible disclosure of 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.
