Jan 4 CVE-2009-4324 with Backdoor:Win32/Bifrose.gen!E 研討會]2010 Being Global and Local研討會 from politic@ntu.edu.tw Mon, 4 Jan 2010 15:57:28


Most likely CVE-2009-1862. Carries Backdoor:Win32/Bifrose.gen!E

After a bit of playing with pdf-parser.py, I think it is CVE-2009-4324. Maybe something else,  you are welcome to check :)  I thought it was CVE-2009-1862 first just based on how some antivirus providers detected it but I was wrong. Wepawet did not detect it as malicious, same situation as Bojan had -see Sophisticated, targeted malicious PDF documents exploiting CVE-2009-4324

I also first got the same error



I think the screenshot below shows that it is CVE-2009-4324
