Description |
A remote stack-based buffer overflow exists in Microsoft Internet Explorer. The browser's vml rendering engine fails to check the length of a fill parameter on the rect tag resulting in a stack-based buffer overflow. With a specially crafted request that contains a vml graphic, an attacker can cause arbitrary code execution resulting in a loss of integrity. |

Solution |
Microsoft has released a patch to address this issue. Additionally, it is possible to correct the flaw by implementing the following workaround(s): Disable active scripting, or change the access control list of vgx.dll. It has been reported that those recommendations have been reported to be unsuccessful. To un-register Vgx.dll, follow these steps: Click Start, click Run, type "regsvr32 -u "%ProgramFiles%\Common Files\Microsoft Shared\VGX\vgx.dll " (without the quotation marks), and then click OK. |
