This update has been rated as having critical security impact by the Red Hat Security Response Team. RealPlayer is a media player that provides media playback locally and via streaming. A buffer overflow bug was discovered in the way RealPlayer processes Flash Media (.swf) files. It is possible for a malformed Flash Media file to execute arbitrary code as the user running RealPlayer. The Common Vulnerabilities and Exposures project assigned the name CVE-2006-0323 to this issue. All users of RealPlayer are advised to upgrade to this updated package, which contains RealPlayer version 10.0.7 and is 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.
