Hello list,

this is to inform you about a local root exploit I found in usbview [1]
release 2.1. This finding was embargoed for 7 days on the linux-distros
mailing list and the fix has been published today.

The upstream author Greg KH is currently working on an improved version
of usbview that will no longer require root privileges to run.

That new version is now released as 3.0, which should prevent the need
for any of this mess in the future as no root permissions are needed at
all.

thanks,
