The Apple Mac OS X “com.apple.AppleDiskImageController” Memory Corruption Vulnerability” isn’t a security flaw at all, let alone a critical, highly critical, or warn-everyone-via-the-BBC type event,” Alastair J. Houghton reports for Alastair’s Place.
Houghton reports, “Now, I should say, that I’m wary of suggesting that disk images are totally safe. There’s a lot of code involved in mounting and reading/writing a disk image, and quite a bit of that runs in kernel mode. But I am pretty peeved at the way that this issue has been so widely publicised, attracting a great deal of attention for lmh and MoKB, when in actual fact there is no such security flaw.”
The Apple Mac OS X “com.apple.AppleDiskImageController” Memory Corruption Vulnerability” is nothing more than a “bug that causes a kernel panic. Not a security flaw. Not a memory corruption bug. Just a completely orderly kernel panic. There aren’t even any processor exceptions involved; the path to the panic is perfectly normal non-exceptional code using ordinary function calls,” Houghton reports.

A denial of service attack is when many computers flood your network until it cannot communicate anymore. A kernal panic is a system error and that’s all it is.
Wikipedia Definition of Denial of Service attack.
* Force the victim computer(s) to reset or consume its resources such that it can no longer provide its intended service.
* Obstruct the communication media between the intended users and the victim in such that they can no longer communicate adequately.
I don’t see either of these happening with a simple disk image kernal panic error.
BBC report is so full of it. FUD that is.
I have had two kernel panics since using OS X (2001).
Both occured while waking the machine from sleep.
G4 dual 867 1gb, 160gb, 10.4.8.
Interesting that you raise the BBC’s journalistic integrity..
Believe it or not, I have it in writing that they only published this news item because of the ‘smugness of Mac users over security..’
You can be assured that was not allowed to rest.
“* Force the victim computer(s) to reset”
“I don’t see either of these happening with a simple disk image kernal panic error.”
Doing somehting which causes the OS to panic would be a classic Denial of Service attack.
yeah biased BBC
im sticking with FOX they neva lie
