|
|
This module exploits a vulnerability found in the ActiveX component of Adobe Flash Player
|
|
|
|
|
before 12.0.0.43. By supplying a specially crafted swf file it is possible to trigger an
|
|
|
|
|
integer underflow in several avm2 instructions, which can be turned into remote code
|
|
|
|
|
execution under the context of the user, as exploited in the wild in February 2014. This
|
|
|
|
|
module has been tested successfully with Adobe Flash Player 11.7.700.202 on Windows XP
|
2014-05-04 01:08:00 +00:00
|
|
|
SP3, Windows 7 SP1 and Adobe Flash Player 11.3.372.94 on Windows 8 even when it includes
|
|
|
|
|
rop chains for several Flash 11 versions, as exploited in the wild.
