3) Technical details
|
|
=====================
|
|
|
|
The vulnerability allows a remote attacker to execute malicious code or access to a part of the dynamically allocated memory using a user interaction
|
|
visiting a Web page or open a specially crafted SWF file, an attacker is able to create an “out of bound” memory corruption. A file with an “ActionRecord”
|
|
structure that contain an invalid “ConstantPool” could lead to remote code execution in the context of the current user.
