Adobe Flash Integer Overflow
|
|
Author: Matthew Bergin
|
|
Date: June 15, 2010
|
|
Versions Affected: Flash10e.ocx v10.0.45.2
|
|
Flash10c.ocx v10.0.32.18 r32
|
|
Root Cause: ActionScript, "ActionIf"
|
|
Affect: Denial-of-Service, possible Command Execution
|
|
CVE: CVE-2010-3639
|
|
Desc: When Parsing an ActionIf ActionScript statement four args are passed
|
|
to the function, an integer named i , a ubyte named ActionCode, a ushort
|
|
named Length, and a short named BranchOffset. If the BranchOffset is -305 or
|
|
smaller it will cause an Access Violation when reading data from a
|
|
invalid memory address. The last 16-bits of the address are controlable
|
|
with the size of the BranchOffset argument. Any data which is in a valid
|
|
segment of memory near the controlled address can be read causing Memory
|
|
Disclosure. This would be used well in combination with a memory corruption
|
|
vulnerability in order to bypass ASLR.
|
|
|
|
In doing my initial research I found a lot of interesting things along the way.
|
|
Flash10c is not vulnerable in the same way Flash10e is. I initially discovered
|
|
the integer overflow in Flash10c while fuzzing SWF. I didnt fuzz it via a web
|
|
browser but instead used a free application which uses the modules in a more
|
|
direct manner. Flash10c is not able to be attacked via a browser as far as I
|
|
have been able to tell. However, I have found during my research that Flash10e
|
|
is loaded as a module when any Flash object is encountered. I am unsure as to
|
|
if this is a configuration issue or not. In addition to this, while debugging
|
|
this issue I found that both versions have a self-changing CRC which inhibits
|
|
keeping break points set.
|
|
|
|
Another interesting note is that when confirming the PoC on Flash Movie Player
|
|
i noticed that if you open the file with the File -> Open drop down menu, the
|
|
PoC will not hit the vulnerable code causing a crash. However, if you register
|
|
the swf extension to Flash Movie Player and "double-click" the PoC file to run
|
|
it, Flash Movie Player will hit the vulnerable code every time.
|
|
|
|
The PoC code would be best embedded into HTML for remote attacks but can be
|
|
attacked in any manner in which Flash10c.ocx/Flash10e.ocx are loaded as modules
|
|
into memory.

Fuzzed Application: EolSoft Flash Movie Player (downloads.cnet.com) v1.5
