Successful exploitation of these vulnerabilities may allow execution of arbitrary code, but requires tricking a user into viewing the malicious file. 6) An error when participating in a poll in the WebEx Meeting Center can be exploited to cause a stack-based buffer overflow via a specially crafted ATP (".atp") file. Successful exploitation of this vulnerability may allow execution of arbitrary code, but requires tricking a user into participating in a poll. The vulnerabilities are reported in builds prior to T27LC SP22 and prior to T27LB SP21 EP3. SOLUTION: Update to build T27LC SP22 and T27LB SP21 EP3.
