NVD description

The Windows Forms (aka WinForms) component in Microsoft .NET Framework 1.0 SP3, 1.1 SP1, 2.0 SP2, 3.0 SP2, 4, and 4.5 does not properly initialize memory arrays, which allows remote attackers to obtain sensitive information via (1) a crafted XAML browser application (XBAP) or (2) a crafted .NET Framework application that leverages a pointer to an unmanaged memory location, aka "System Drawing Information Disclosure Vulnerability."

    CVE-2013-0001 | A notepad that was never erased Imagine handing someone a used notepad with private writing still on it. In several .NET Framework versions, Windows Forms did not properly initialize memory arrays. A crafted application could use this flaw to expose sensitive information. The official record describes crafted XAML browser applications or .NET applications accessing unmanaged memory. This is information disclosure, not a claim of arbitrary code execution. The lesson: initialize memory before handing it to another part of a program.
