Cisco WebEx WRF Player Vulnerabilities
Cisco today released details of a set of buffer overflow vulnerabilities and fixes for their WebEx WRF player. The exploits describe multiple buffer overflows caused by a maliciously crafted WRF file (generally posted on a website), or by attending a WebEx meeting with an attacker attending. The results of the exploit can result in execution of arbitrary code on the target system.
The exploits are categorized as: CVE-2009-2875, CVE-2009-2876, CVE-2009-2877, CVE-2009-2878, CVE-2009-2879 and CVE-2009-2880.
The WebEx site itself has the fixed client code. If you have an inhouse WebEx server, updating the server updates all the clients (as they connect). You won't find an easier to install fix than this one!
From the Cisco advisory, the "first fixed" releases are listed below, by Major Release and Client OS. All versions subsequent to these are fixed as well.
