Cisco Security Advisory: Multiple Vulnerabilities in the Cisco WebEx Recording
Format and Advanced Recording Format Players
Advisory ID: cisco-sa-20130904-webex
Revision 1.0
For Public Release 2013 September 4 16:00 UTC (GMT)
+---------------------------------------------------------------------
Summary
=======
Multiple buffer overflow vulnerabilities exist in the Cisco WebEx Recording
Format (WRF) and Advanced Recording Format (ARF) Players. Exploitation of
these vulnerabilities could allow a remote attacker to crash an affected
player, and in some cases, 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.
Cisco has updated affected versions of the Cisco WebEx Business Suite meeting
sites, Cisco WebEx 11 meeting sites, Cisco WebEx Meetings Server, and Cisco
WebEx WRF and ARF Players to address these vulnerabilities.
Cisco has released free software updates that address these vulnerabilities.
