Maybe I am missing something, but at least for me, modprobe vulnerabilities are exploitable via privledged networking services, nothing more.

Maybe not. ncpfs for instance has an ioctl that seems to allow unprivileged users to specify a character set (codepage in m$speak) that's requested via load_nls(), which in turn does a

Then it looks like the driver is broken, not modutils.

Well, you can use this ioctl only before ncp filesystem gets to life, but yes, as this call is always done by mount process, I'll add

if (!capable(CAP_SYS_ADMIN))
return -EPERM;

here. But I still do not see any problem, as ncpfs limits charset/codepage length to 20 chars (+ NUL terminator), and nobody told me that it is not possible to use " or - in codepage name ;-)

#1 lore raw

test11-pre5 breaks vmware

Hi Petr,

You probably noticed this already but I just wanted to bring it to your attention that /usr/bin/vmware-config.pl script needs updating since the flags in /proc/cpuinfo is now called "features" so it otherwise fails complaining that my 2xP6 has no tsc. Trivial change but still worthy of propagating into your latest .tar.gz file for 2.4.x

Regards,
Tigran
