Identify key improvements needed for stunnel on Red Hat Linux 7.2 due to a significant format string flaw. Execute remedial steps without delay.
Updated stunnel packages are now available for Red Hat Linux 7.2

Solution

Before applying this update, make sure you have applied all previously released errata relevant to your system.

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.
