ATmaCA has discovered a vulnerability in Process Explorer, which potentially can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a boundary error when handling overly long "CompanyName" VersionInfo data of a running process. This can be exploited to cause a stack-based buffer overflow and may allow execution of arbitrary code.
Successful exploitation requires that a user runs a specially crafted program and convinces the administrator to view the properties of the malicious running process.
The vulnerability has been confirmed in version 9.12, and also reported in version 9.23. Other versions may also be affected.
