'Name' => 'Sun Java JRE AWT setDiffICM Buffer Overflow',
'Description' => %q{
This module exploits a flaw in the setDiffICM function in the Sun JVM.
The payload is serialized and passed to the applet via PARAM tags. It must be
a native payload.
The effected Java versions are JDK and JRE 6 Update 16 and earlier,
JDK and JRE 5.0 Update 21 and earlier, SDK and JRE 1.4.2_23 and
earlier, and SDK and JRE 1.3.1_26 and earlier.
NOTE: Although all of the above versions are reportedly vulnerable, only
1.6.0_u11 and 1.6.0_u16 on Windows XP SP3 were tested.
