Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Apple QuickTime. User interaction is required to
exploit this vulnerability in that the target must visit a malicious page or
open a malicious file.
The specific flaw exists within the 'mvhd' atom. By providing a malformed
version and flags, an attacker is able to create controllable memory
corruption, and trigger an arbitrary write operation. By exploiting this, an
attacker could execute code in the context of the current user.
