Subject: [PATCH 00/20] world-writable files in sysfs and debugfs
Date: Fri, 4 Feb 2011 15:22:29 +0300	[thread overview]
Message-ID: <cover.1296818921.git.segoon@openwall.com> (raw)

The search was made with trivial shell commands:

find | xargs grep S_IWUGO
find | xargs grep S_IWOTH

I didn't precisely investigate how exactly one may damage the
system/hardware because of issues number, maybe the harm is very limited
in case of some of these drivers.

One suspicious file is ./staging/speakup/speakup.h, but it explitly calls
macros as world-writable.  I didn't check what speakup's world-writable
files provide because it requires some knowledge about the hardware.
