Summary: CA products that implement the DSM gui_cm_ctrls ActiveX
control contain a vulnerability that can allow a remote attacker
to cause a denial of service or execute arbitrary code. The
vulnerability, CVE-2008-1786, is due to insufficient verification
of function arguments by the gui_cm_ctrls control. An attacker can
execute arbitrary code under the context of the user running the
web browser.

Desktops, only the server installation is affected. Client
installations are not affected. For CA Desktop Management Suite,
Unicenter Desktop Management Bundle, Unicenter Asset Management,
