Russinovich: A possible cure for exploitable heap corruption in Windows 7 | |
|
||
| Time: 05:35 EST/10:35 GMT | News Source: BetaNews | Posted By: Kenneth van Surksum | ||
|
The key to a huge plurality, if not a majority, of exploits that have plagued Microsoft Windows over the past two decades has been tricking the system into executing data as though it were code. A malicious process can place data into its own heap -- the pile of memory reserved for its use -- that bears the pattern of executable instructions. Then once that process intentionally crashes, it can leave behind a state where the data in that heap is pointed to and then executed, usually without privilege attached. |
