Yes, you are right... but... I saw that hole after installing new linx and
checked it's security. First I was suprised but not for a long time.
In a few mins I noticed all linux versions are chown .kmem; chmod g+s
lsof... on linux /dev/kmem is +w for gid kmem, on bsd too (probably, I
didn't checked that), so... all of std. distributions are vuln. without
ONE! the slackware, IMHO, it's the most secure distribution [ :))) i know:
slackware doesn't has lsof;))) but by tahat way that distr. is secure ;P ]
Cheers
