Stack-based buffer overflow in the animated cursor code in Microsoft Windows 2000 SP4 through Vista allows remote attackers to execute arbitrary code or cause a denial of service (persistent reboot) via a large length value in the second (or later) anih block of a RIFF .ANI, cur, or .ico file, which results in memory corruption when processing cursors, animated cursors, and icons, a variant of CVE-2005-0416, as originally demonstrated using Internet Explorer 6 and 7. NOTE: this might be a duplicate of CVE-2007-1765; if so, then CVE-2007-0038 should be preferred.

Unspecified vulnerability in Microsoft Windows 2000 SP4 through Vista allows remote attackers to execute arbitrary code or cause a denial of service (persistent reboot) via a malformed ANI file, which results in memory corruption when processing cursors, animated cursors, and icons, a similar issue to CVE-2005-0416, as originally demonstrated using Internet Explorer 6 and 7. NOTE: this issue might be a duplicate of CVE-2007-0038; if so, then use CVE-2007-0038 instead of this identifier.

The Windows Animated Cursor (ANI) capability in Windows NT, Windows 2000 through SP4, Windows XP through SP1, and Windows 2003 allows remote attackers to execute arbitrary code via the AnimationHeaderBlock length field, which leads to a stack-based buffer overflow.
