Microsoft Acknowledges One IE7 Flaw, Denies Another

Microsoft today acknowledged that one of two IE7 security flaws alleged by Denmark-based security firm Secunia could leave systems vulnerable.

In a post made today on Microsoft's Security Response Center Blog, Christopher Budd wrote that the company is investigating a URL display issue that might be exploitable to phishing attacks via spoofing.

"We're not aware of any attacks that are attempting to use this," he wrote, "but as always we will continue to monitor the situation throughout our investigation."

Recommendations for protecting systems while the issue is being investigated can be found in the blog post here.

Microsoft refutes another report from Secunia that alleges IE7 also suffers from URL redirect issues that could leave users vulnerable.

"These reports are technically inaccurate," Budd wrote on Friday, one day after Secunia published its report and two days after IE7's release. "The issue concerned in these reports is not in Internet Explorer 7 (or any other version) at all. Rather, it is in a different Windows component, specifically a component in Outlook Express. While these reports use Internet Explorer as a vector, the vulnerability itself is in Outlook."

He continued, "We do have this under investigation and are monitoring the situation closely, and we'll take appropriate action to protect our customers once we've completed the investigation."

Secunia rates both flaws as "less critical."
