Descriptions
Microsoft Data Access Components (MDAC) 2.8 SP1 and SP2, and Windows Data Access Components (WDAC) 6.0, does not properly validate memory allocation for internal data structures, which allows remote attackers to execute arbitrary code, possibly via a large CacheSize property that triggers an integer wrap and a buffer overflow, aka "ADO Record Memory Vulnerability." NOTE: this might be a duplicate of CVE-2010-1117 or CVE-2010-1118.
Microsoft Data Access Components (MDAC) versión 2.8 SP1 y SP2 y Windows Data Access Components (WDAC) versión 6.0 no valida apropiadamente la asignación de memoria para las estructuras de datos internas, lo que permite a los atacantes remotos ejecutar código arbitrario, posiblemente por medio de una propiedad CacheSize larga que desencadena un ajuste de enteros y un desbordamiento del búfer, también se conoce como "ADO Record Memory Vulnerability" Nota: este CVE podría ser un duplicado de CVE-2010-1117 o CVE-2010-1118.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. This vulnerability was submitted to the ZDI via at the annual Pwn2Own competition at CanSecWest. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The flaw exists within the MSADO component. When handling the a user specified CacheSize property the process uses this value to calculate the 'real' cache size. This value is used without proper validation. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the browser.
