The bug is a buffer overflow in the SaveAs function of Chrome version 0.2.149.27. If the user accesses a website containing exploit codes, the attacker will then execute the malicious codes and seize the control of the PC.
Today, Microsoft also confirmed the critical flaw in Windows Media Encoder identified by two Bkis researchers Nguyen Minh Duc and Le Manh Tung and issued the update.

"We have set targets to master security technologies to help ensure the national security as well as enter the global market step by step. Four years ago, we began to train our researchers, build our network security laboratory, improve the research process and analyze software vulnerabilities. And now we've got ready for challenges. As I many times have said, Vietnamese are competent in this area," said Nguyen Tu Quang, Director of Bkis.
Additional information about Google Chrome's vulnerability:
