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 code responsible for parsing a DEMX RIFF chunk within Director files. The logic within the TextXtra.x32 module fails to account for a specific condition and can be made to misallocate a buffer on the heap. By crafting specific values within DEMX substructures an attacker can corrupt memory leading to arbitrary code execution under the context of the user running the browser.
