Description Josh Bressers 2005-07-11 22:48:40 UTC

sysreport creates a temporary directory in an insecure manner.

umask 0077
ROOT=/tmp/sysreport.$$

ROOT should be something like
ROOT=`mktemp -d /tmp/sysreport.XXXXXXXX`

It is possible for a local attacker to cause a race condition and trick
sysreport into writing its output to a directory the attacker can read.
