2011年2月23日
  危険度: : 高
  CVE識別番号: CVE-2010-1098

  概要

Microsoft Windows is prone to a remote denial-of-service vulnerability when processing '.ani' files. Successful exploits will cause the vulnerable applications that use the affected APIs to crash or become unresponsive, denying service to legitimate users. The ANI parser in Microsoft Windows before 7 on the x86 platform, as used in Internet Explorer and other applications, allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted biClrUsed value in the BITMAPINFO header of a .ANI file.
