One IE flaw leads to another
The new bug could be used to launch code execution attacks. Microsoft acknowledged that the vulnerability, found by Andreas Sandblad of Secunia, is not just a successful exploit of the flaw uncovered last week by Michal Zalewski.
It was originally believed that the flaw found by Sandblad was related to the one discovered by Zalewski, but a Microsoft representative confirmed that the two vulnerabilities are separate.
"During analysis, Secunia discovered a variant of this vulnerability," security company Secunia wrote on its Web site on Tuesday, referring to the bug found by Zalewski. The company confirmed the problem "on a fully patched system with Internet Explorer 6.0 and Microsoft Windows XP SP2."
Both flaws could be used to corrupt a PC's memory if the computer's user can be tricked into visiting a malicious Web site, Secunia said.
Secunia added that Microsoft is working on a patch.
