DESCRIPTION:
Multiple vulnerabilities have been reported in Cisco WebEx Player,
which can be exploited by malicious people to compromise a user's
system.
1) An unspecified error when processing WebEx Recording Format (WRF)
or Advanced Recording Format (ARF) files can be exploited to cause a
buffer overflow via a specially crafted file.
2) An unspecified error when processing WebEx Recording Format (WRF)
or Advanced Recording Format (ARF) files can be exploited to cause a
buffer overflow via a specially crafted file.
3) An unspecified error when processing WebEx Recording Format (WRF)
or Advanced Recording Format (ARF) files can be exploited to cause a
buffer overflow via a specially crafted file.
4) An unspecified error when processing WebEx Recording Format (WRF)
or Advanced Recording Format (ARF) files can be exploited to cause a
buffer overflow via a specially crafted file.
5) A boundary error when processing a recording of a session in the
WebEx player can be exploited to cause a stack-based buffer overflow
via a specially crafted WebEx Recording Format (WRF) file.
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.
PROVIDED AND/OR DISCOVERED BY:
5, 6) Federico Muttis, Sebastian Tello, and Manuel Muradas, Core
Security Technologies.
Remaining vulnerabilities reported by the vendor, TippingPoint, and
Fortinet's FortiGuard Labs.
