Buffer Overflow Vulnerabilities in the Cisco WebEx Player
cisco-sa-20120404-webex · NA · Published · Updated
The Cisco WebEx Recording Format (WRF) player contains three buffer overflow vulnerabilities. In some cases, exploitation of the vulnerabilities could allow a remote attacker to execute arbitrary code on the system with the privileges of a targeted user. The Cisco WebEx Players are applications that are used to play back WebEx meeting recordings that have been recorded on a WebEx meeting site or on the computer of an online meeting attendee. The players can be automatically installed when the user accesses a recording file that is hosted on a WebEx meeting site. The players can also be manually installed for offline playback after downloading the application from www.webex.com. If the WRF player was automatically installed, it will be automatically upgraded to the latest, nonvulnerable version when users access a recording file that is hosted on a WebEx meeting site. If the WRF 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 updated affected versions of the WebEx meeting sites and WRF player to address these vulnerabilities.
