TITLE

Cisco WebEx Recording Format player Vulnerable to buffer overflow

DESCRIPTION

Buffer overflow in the Cisco WebEx Recording Format (WRF) player T27 L through SP11 EP26, T27 LB through SP21 EP10, T27 LC before SP25 EP11, T27 LD before SP32 CP2, and T28 L10N before SP1 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted WRF file, aka Bug ID CSCtz72946. Cisco WebEx Recording Format (WRF) player Contains a buffer overflow vulnerability. Cisco WebEx is prone to multiple remote buffer-overflow vulnerabilities because it fails to perform adequate boundary-checks on user-supplied data. An attacker can exploit these issues to execute arbitrary code with the privileges of the affected application. Failed exploit attempts will result in a denial-of-service condition. Cisco WebEx is a set of Web conferencing tools developed by American Cisco (Cisco), which can assist office workers in different places to coordinate and cooperate. WebEx services include Web conferencing, telepresence video conferencing and enterprise instant messaging (IM). ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!

Successful exploitation of the vulnerabilities may allow execution of arbitrary code. The vulnerabilities are reported in the following versions: * Client builds 28.0.0 (T28 L10N). * Client builds 27.32.1 (T27 LD SP32 CP1) and prior. * Client builds 27.25.10 (T27 LC SP25 EP10) and prior. * Client builds 27.21.10 (T27 LB SP21 EP10) and prior. * Client builds 27.11.26 (T27 L SP11 EP26) and prior. SOLUTION: Update to a fixed client build (please see the vendor's advisory for details). PROVIDED AND/OR DISCOVERED BY: The vendor credits iDefense and Microsoft Vulnerability Research (MSVR).
