Cisco WebEx Network Recording Player Multiple Buffer Overflow Vulnerabilities

Multiple buffer overflow vulnerabilities exist in the Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) files. An attacker could exploit these vulnerabilities by providing a user with a malicious ARF file via email or URL and convincing the user to launch the file. Exploitation of these vulnerabilities could cause an affected player to crash and, in some cases, could allow arbitrary code execution on the system of a targeted user.

The Cisco WebEx Network Recording Player is an application that is used to play back WebEx meeting recordings that have been recorded on the computer of an online meeting attendee. The player can be automatically installed when the user accesses a recording file that is hosted on a WebEx server.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
