Before the sun set on Microsoft&#39;s Patch Tuesday this month, security firm Secunia discovered a vulnerability in Firefox that malicious hackers could exploit to compromise a user&#39;s system. Here&#39;s the catch: Exploiting the bug depends on interaction between Mozilla&#39;s browser and Microsoft&#39;s Internet Explorer.

(InfoWorld) - Mozilla's security chief Tuesday panned a pair of Firefox bugs revealed Monday as low-level threats but hours later changed her mind and said that when used together, they could pose a greater risk. The researcher who disclosed the vulnerabilities agreed with her. Mostly. Michael Zalewski, who regularly publishes browser flaw findings, on Monday posted details on the Full-disclosure mailing list about four browser vulnerabilities, including two affecting Firefox. He categorized one as a "major" threat, and he saw the other as only a "medium" threat. In an entry on the Mozilla security blog -- which debuted last week -- Window Snyder, the company's chief security officer, said the more serious of the two bugs found by Zalewski was no more than a spoofing vulnerability and deserved only a "low" rating. "This is unsafe because it could be used to lure a user to enter content into the spoofed frame but does not result in code execution," said Snyder. "[For example] this might be used with phishing attacks." Her take doesn't jibe with Zalewski's contention that the flaw can be used to stick malicious code onto the victimized computer. "By my book, [this is] more serious than just spoofing, so I marked it as 'major,' whereas Mozilla still considers it to be a typical case of spoofing ('low')," said Zalewski in an e-mail interview Wednesday. "But it would be inaccurate to say that Window's assessment contradicts my analysis." Later Tuesday, Snyder updated her blog, saying that after further review, "these two bugs may be used together to allow an attacker to access any file the user has access to on the system. If this is the case, that may change the severity rating to 'medium'." Zalewski dismissed the idea that he and Mozilla's Snyder were at odds and instead turned attention to what he thinks is most important. "All in all, I think we pretty much agree here," he said. "The big issue [of the four vulnerabilities] was the Microsoft Internet Explorer flaw. The other three are important, but not critical." According to entries in Mozilla's Bugzilla, the more serious of the two Firefox flaws has not yet been assigned to someone for a fix. Snyder, meanwhile, said that the Mozilla security team is looking into changes to improve content handler management, the root cause of the bug she pegged as "low." Zalewski on Monday noted on the Full-disclosure mailing list that it appears Apple's Safari browser is also vulnerable to same bug he found in IE6 and IE7 and labeled "critical." Tuesday, Kevin Finisterre, a researcher known for the "Month of Apple Bugs" project in January, confirmed Zalewski's Safari suspicions. Apple officials did not reply to a request for comment.

(InfoWorld) - Makers of some of the most popular extension software used by the Firefox browser are not doing enough to secure their software, a security researcher said Wednesday. The problem is that many widely used Firefox extensions, including toolbars from Google, Yahoo, and AOL, do not use secure connections to update themselves, according to Christopher Soghoian, a security researcher who blogged about the issue on Wednesday. Soghoian is best known as the researcher who attracted the attention of the FBI late last year after publishing a tool that could be used to print fake boarding passes. The Indiana University doctoral student discovered the Firefox issue last month while examining network traffic on his computer. He noticed that many of the most popular Firefox extensions are not hosted on servers that use the SSL Web protocol. SSL Web sites, which begin with "https://," use digital certificates to provide users with some level of assurance that they're not connecting with a fake server. Although the corporation behind Firefox, Mozilla, hosts the majority of Firefox extensions on its own SSL-enabled Web site, it is common for commercial extension-makers like Google to host their software on an unsecured site, Soghoian said in an interview. This leaves users vulnerable to a "man-in-the middle" attack, where Firefox could be tricked into downloading malicious software from a site it mistakenly thought was hosting an extension. It wouldn't be easy for an attacker to pull this off, however. In one scenario, the hacker would set up a malicious wireless access point in a public area where people are using wireless connections. He could then redirect extension update traffic to a malicious computer. "An attacker who sets up a wireless access point can then infect anyone who connects to it," Soghoian said. The Del.icio.us Extension, Facebook Toolbar, Ask.com Toolbar, LinkedIn Browser Toolbar, Netcraft Anti-Phishing Toolbar, and PhishTank SiteChecker are also vulnerable to this issue, Soghoian said. Though Soghoian said Firefox users should avoid extensions that are not from the secure Firefox add-ons site, not all security researchers see this as a major issue. "It's just yet another vulnerable design among billions,"said Gadi Evron, security evangelist for Beyond Security. "I don't see it as that critical. There is no inherent vulnerability, but it does make the over-whole design weaker, and that should probably be addressed" Evron said it was "silly" that sites weren't using SSL for these extensions. Soghoian said he notified Google, Yahoo, and Facebook of the issue in mid-April, but nobody had addressed the issue as of Wednesday. Just hours after Soghoian went public with his findings, Google said it would "soon" have a fix for the problem. It's common for Web developers to ignore security in the rush to push out new and cool features, Soghoian said. "Your average Web 2.0 developer doesn't learn about security," he said. "Google has a spectacular security team ... my suspicion is that one hand wasn't talking to the other."
