Date Discovered April 13, 2010
Description Microsoft Visio is prone to a remote code-execution vulnerability. This issue arises when the application processes a malicious file.
Attackers can exploit this issue to execute arbitrary code in the context of the user running the application. Failed exploit attempts will result in a denial-of-service condition.
- Microsoft Visio 2002 SP2
- Microsoft Visio 2003 SP3
- Microsoft Visio 2007 SP1
- Microsoft Visio 2007 SP2
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.
Deploy network intrusion detection systems to monitor network traffic for malicious activity. Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from a successful exploit.
Do not accept or execute files from untrusted or unknown sources. To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.
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 exploit attempts of memory-corruption vulnerabilities.
The vendor has released an advisory and fixes. Please see the references for more information.
