Descriptions

Stack-based buffer overflow in the HrShellOpenWithMonikerDisplayName function in Microsoft Hyperlink Object Library (hlink.dll) allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long hyperlink, as demonstrated using an Excel worksheet with a long link in Unicode, aka "Hyperlink COM Object Buffer Overflow Vulnerability." NOTE: this is a different issue than CVE-2006-3059.

Un desbordamiento de búfer basado en pila en la función HrShellOpenWithMonikerDisplayName en la Biblioteca de objetos de Hipervínuclo de Microsoft (hlink.dll) permite a atacantes remotos causar una denegación de servicio (caída de la aplicación) y posiblemente ejecutar código de su elección a través de un hipervínculo demasiado largo, tal y como se demuestra con una hoja de cálculo Excel con un enlace en Unicode demasiado largo. Se trata de un problema también conocido como "vulnerabilidad de desbordamiento de búfer del objeto hipervínculo COM." NOTA: se trata de un problema diferente al del CVE-2006-3059.
