Possible security issue

Check to see if you have a problem, especially if you have wine installed.

Re: Possible security issue

I read the article and checked for the vulnerability on my laptop:

me$ cat /proc/sys/vm/mmap_min_addr
me$ 0

Yup, it's there for me. Since I just installed wine on here this morning, I checked to see if changing the value as suggested prevented wine from working properly. It had no effect.

I am running karmic on my laptop. So this might be there for others as well. I don't really know what security problems this opens up. Thanks for the link Detonate.

Re: Possible security issue

Mine was OK. But if you set a non-zero value, you have to reset it after each re-boot; or follow the special instructions to make the fix permanent.

Re: Possible security issue

According to what I read, if it is set to Zero, it opens a possibility for a non-root privileged user to gain root rivileges.

reports that Ubuntu sets this value to 65535 which means there is no problem if you run Kubuntu.

Re: Possible security issue

But if you install wine, it seems to change it.

I missed that thread, or I would not have double posted.

I would not even know had you not posted. Oh well.
