Microsoft Internet Explorer ADODB.Recordset Double Free Memory Exploit (ms07-009).
|
|
**********************************************************************************
|
|
Review:
|
|
This code exploit "double free error" in msado15.dll NextRecordset() function.
|
|
As a result of double freeing of same string, rewriting of Heap Control Block
|
|
by malicious data is occuring.
|
|
Technique of exploitation is based on "Lookaside remapping".
|
|
Runs calc.exe if success.
