- Microsoft Windows Object Linking and Embedding (OLE) Automation is prone to a remote code-execution vulnerability due to an integer overflow error. An attacker can exploit this issue by enticing an unsuspecting user to view a malicious webpage or a specially crafted file. Successful exploits will allow the attacker to execute arbitrary code in the context of the user running the application, which can compromise the application, and possibly, the computer.

Run all software as a nonprivileged user with minimal access rights.To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.
Do not accept or execute files from untrusted or unknown sources.Never accept files from untrusted or unknown sources, because they may be malicious in nature. Avoid opening email attachments from unknown or questionable sources.
Do not follow links provided by unknown or untrusted sources.Attackers could exploit this vulnerability by enticing a user to visit a malicious website. Do not follow links provided by sources of questionable integrity.
Set web browser security to disable the execution of script code or active content.Disable support for script code and active content within a client browser to reduce the chances of a successful exploit. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.
Implement multiple redundant layers of security.Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.
