Security flaws surface in Leopard, VPN

Security flaws in Leopard

A new denial of service (DoS) vulnerability has surfaced in Apple's Mac OS X Leopard operating system that can result in crashes, according to Heise Security. The flaw, which is an integer overflow in the load_threadstack function in mach_loader.c, occurs when processing Mach-O binaries and can lead to a kernel panic. Single user systems should not be at risk, according to the company, but multi-user setups are vulnerable because attackers do not require any special privileges to provoke the error.

Additionally, security website digit-labs.org has reported a DoS vulnerability in the VPN (Virtual Private Network) service in Mac OS X 10.5 where maliciously-crafted packets can cause the service to freeze. Demonstration exploits are available for both flaws, and no patches have been released to correct the problems.

Heise must have a team of people doing nothing but trying to find ways to crash OSX.

None of this c*** they publish is in the wild - they are all (wow, what a surprise) only in their own lab. Now, if they were actually an ethical company they would notify Apple of the problem and allow them to issue a notice or make corrections - instead of using their self-made flaws as a way to extend their own business.

Well said, Doofuses.

I'd also like to point out that there are obviously many people trying their darndest to find vulnerabilities. It's good to see that none have managed to gain control of someone else's Mac yet.

what happened the other day_ Except that I was merely trying to access the internet and my system crashed_ I don't think I was hacked" per se_

BUT Leopard is buggy as hell_

Oh yeah - has anyone found out who this no-name company that keeps feeding MacNN retarded info about OS X actually is? This is their claim to fame? 2 mentions of OS X flaws in a couple of weeks_ Also seems like MacNN are the only folks reporting these Heise found vulnerabilities_

MacNN - how much are they paying you to run their news story? Really! It's okay - you can tell us - we won't rat you out_

Where would you rather the exploit potentials be found, when it reaches the wild?

And where do you think most of the Windows vulnerabilities are found? In the wild? No, usually by hackers/groups looking for vulnerabilities to report them, not to exploit them.

10.5 is *not* "buggy as

h***". there are some bugs, to be sure. buggy as h***, well, that seems patently untrue, not just a silly exaggeration.

and, agree on all the heise comments. losers. i'm glad people are hacking and poking at leopard, but... every little stack overflow they can evoke doesn't require a bloody press release. if we look close enough, i'm sure we'll find a nice stack of microsoft checks stubs in heise's bank accounts...
