Description Josh Bressers 2005-07-11 18:54:20 EDT
+++ This bug was initially created as a clone of Bug #162978 +++

sysreport creates a temporary directory in an insecure manner.

umask 0077

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.
