Synopsis: gftp format string vulnerability corrected Advisory

1. Topic:
An updated gftp package is available for Red Hat Linux 6.2 and
7.1. This package contains an upgrade to gftp version 2.0.8, which
improves functionality and fixes a format string vulnerability.
2. Relevant releases/architectures:
Red Hat Linux 6.2 – alpha, i386, sparc
Red Hat Linux 7.0 – alpha, i386
Red Hat Linux 7.1 – i386
3. Problem description:
Previous gftp versions had a problem with format strings
allowing malicious ftp servers to potentially execute code on the
gftp user’s system.
4. 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.
