Multiple buffer overflow vulnerabilities exist in the Cisco WebEx Recording Format (WRF) and Advanced Recording Format (ARF) Players. In some cases, exploitation of the vulnerabilities could allow a remote attacker to execute arbitrary code on the system of a targeted user. The Cisco WebEx Players are applications that are used to play back WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The players can be automatically installed when the user accesses a recording file that is hosted on a WebEx server. The player can also be manually installed for offline playback after downloading the application from www.webex.com. If the WebEx recording player was automatically installed, it will be automatically upgraded to the latest, non-vulnerable version when users access a recording file that is hosted on a WebEx server. If the WebEx recording player was manually installed, users will need to manually install a new version of the player after downloading the latest version from www.webex.com. Cisco has released free software updates that address these vulnerabilities.
