Description

A buffer overflow exists in Windows. msiexec.exe fails to validate GUID strings passed to the /x uninstall option resulting in a buffer overflow. With a specially crafted command, a context-dependent attacker can cause arbitrary code execution resulting in a loss of integrity.

Classification

Location: Local / Remote, Context Dependent
Attack Type: Input Manipulation
Impact: Loss of Confidentiality, Loss of Integrity
Solution: Workaround
Exploit: Exploit Public
Disclosure: OSVDB Verified, Vendor Verified, Uncoordinated Disclosure

Technical

The Globally Unique Identifier is converted to Unicode then pushed onto the stack, allowing for complete overwrite of the Structured Exception Handler.

This is generally a local buffer overflow, however some ActiveX controls are known to call this command, allowing for remote code execution in some scenarios.

Solution

None at this time. Set the killbit on untrusted ActiveX controls.
