Description Lubomir Kundrak 2007-01-15 13:30:19 UTC
Description of problem:

Stack based buffer overflow occurs, when gnome-system monitor is launched
while process that has a file with too long filename mapped in its address
space (visible via /proc/$PID/maps), and could potentially lead to arbitrary
code execution (mitigated by SSP).

Version-Release number of selected component (if applicable):

At least FC6 and RHEL5 libgtop2.

How reproducible:

Always.

Steps to Reproduce:

# Create a file with too long pathname. Some filesystems limit filenames
# to 255 characters, so use a deep directory hierarchy instead
export dir=$(perl -e " print 's/'x1000;")
mkdir -p $dir

# Copy a binary image thata will get mapped upon execution there and run it.
# Sleep will harmlessly run for some time...
cp /bin/sleep $dir
$dir/sleep 100 &

# Run system monitor while the program is running
gnome-system-monitor

Actual results:

*** stack smashing detected ***: gnome-system-monitor terminated

Expected results:

Gnome-system-monitor should help us on our way to salvation,
eternal and everlasting love and peace.
