Microsoft · Internet Explorer · CVE-2010-1098
**Name of the Vulnerable Software and Affected Versions**
Microsoft Windows versions prior to 7
**Description**
The issue allows remote attackers to cause a denial of service, consuming memory and CPU, via a crafted `biClrUsed` value in the `BITMAPINFO` header of a .ANI file. This is related to the ANI parser in Microsoft Windows, which is used in Internet Explorer and other applications.
**Recommendations**
For versions prior to 7, update to a newer version to mitigate the risk. As a temporary workaround, consider avoiding the use of .ANI files or restricting access to them until a patch is available.
