From: segoon@openwall.com (Vasiliy Kulikov) To: linux-arm-kernel@lists.infradead.org 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.
