The GDI+ library 'GdiPlus.dll' provides access to a number of graphics methods, via a class based API. For more information on GDI+, please visit following URL.
Tagged Image File Format (TIFF) is a container format for storing images. For more information about TIFF, please visit following URL.
Remote exploitation of a heap based buffer overflow vulnerability in Microsoft Corp.'s Windows GDI+ could allow an attacker to execute arbitrary code with the privileges of the current user.
This vulnerability occurs when parsing a malformed TIFF file. By supplying incorrect values in a BitsPerSample tag, it is possible to trigger a heap based buffer overflow.
Successful exploitation allows an attacker to execute arbitrary code in the context of the current user. Social engineering is required, as an attacker must trick a user into viewing an image in the Web Browser, viewing an e-mail with embedded image, opening an office file with embbeded image, or downloading an image file and opening it within a graphics rendering program.
