Google on Security Alert

Google on Security Alert


Though the New Years holiday was a long vacation for many, it was a long work weekend for those in Google's security operations.

A flaw was reported and fixed over the weekend, and there are allegations in the wild that a new crop of security issues may still exist.

Heather Adkins, information security manager at Google, said in a statement e-mailed to internetnews.com that over the holiday weekend Google was notified of a vulnerability that spanned multiple Google products.

"We were first notified that this issue affected Google Video and fixed it within a few hours of receiving the report," Adkins stated. "We were then notified that the same issue affected other Google products. The problem with the other products was resolved within 24 hours of the second report. To our knowledge, no one exploited the vulnerability and no users were impacted."

The vulnerability, if exploited, could have allowed Google users' Gmail contact lists and other information to be exposed to malicious attackers. Adkins noted that the vulnerability related to how Google uses certain JSON (JavaScript Object Notation) (define) object within some of its product code.

"The fix we employed made sure the objects could not be abused," Adkins said. Google engineer Matt Cutts wrote in a blog that Google fixed the JSON vulnerabilities with a number of different approaches.

"On some of them, we immediately fixed the code to properly stop JavaScript," Cutts wrote. "On others, the urls were blocked until the next push of that service will happen."

Cutts noted that since the issues were server side, as Google's applications are Web-based, the fixes were deployed much faster than they would have been had the vulnerabilities appeared client-side.

"Even this situation (where several Google properties needed to be changed) yielded a much faster fix than patching so many client-side applications, and much of this was happening on New Year's Eve and New Year's Day when most normal people are sleeping off the night before," Cutts wrote.

Google has a solid track record of fixing vulnerabilities rapidly, especially of late. In mid-December Google moved quickly ahead of a weekend to fix an alleged flaw in its money-making AdWords solution.

In that case the security researcher alerted Google before the vulnerability was publicly disclosed, a move that Google applauded.

Responsible disclosure is something that Google's Adkins is certainly very keen on. "We strongly encourage anyone who is interested in researching and reporting security issues to follow responsible disclosure practices, including giving vendors ample time to respond to reports," Adkins commented.

"Responsible disclosure allows companies like Google to keep users safe by fixing vulnerabilities and resolving security concerns before they are brought to the attention of the bad guys."

There are currently perhaps two other issues lurking in the security shadows for Google. In one particularly active thread in a Google Groups discussion list, posters have alleged that their Gmail e-mails have gone missing or have been deleted. Google apologized in the thread for any inconvenience the issue may be causing.

"Regretfully, a small number of our users -- about 60 -- lost some or all of their email received prior to December 18th," Google spokesperson Courtney Hohne told internetnews.com. "Once we found out about this issue, we worked day and night to confirm that only a few accounts were affected and to do whatever we could to restore as much of the users' accounts as we could."

"We also reached out to the people who were affected to apologize and to work with them to restore the email from any personal backup they might have," Hohne added. "We know how important Gmail is to our users - we use it ourselves for our corporate email. We have extensive safeguards in place to protect email stored with Gmail and we are confident that this is a small and isolated incident."

Security research Rajesh Sethumadhavan posted on another security mailing list that Google's "blacklist" of phishing URLs was now publicly accessible.

Google's Safe Browsing extension is built into the Google Toolbar and integrated into Mozilla Firefox 2.0. Safe Browsing validates URLs against a constantly updated list of known phishing URLs. The problem apparently is that Google may also be catching a bit too much information.

"I just played around a bit with those lists and as it seems, Google did a splendid job, even capturing some people's login data," a poster noted in response to Sethumadhavan.

Money For Vista, IE Bugs

Money For Vista, IE Bugs


The race to pick holes in Microsoft's newest operating system and browser is on.

VeriSign's iDefense Labs has kicked off its Vulnerability Contributor Program (VCP), a challenge to find remote arbitrary code execution vulnerabilities in Vista and Internet Explorer 7.0. VCP will pay $8,000 for the first six confirmed vulnerabilities.

It will pay an additional $2,000 to $4,000 for those who also provide working exploit code for the submitted vulnerability, bringing the total potential bounty to $12,000.

IDefense is looking for vulnerabilities that are remotely exploitable and allow arbitrary code execution without additional user interaction (like clicking an e-mail attachment for example). Social engineering and other attacks that require the user to do something other than actually just browsing a site are not valid for this contest.

IDefense expects to receive well more than six reports of vulnerabilities, but iDefense spokesman Jason Greenwood said the VCP stops at six because of budget constraints.

"We receive hundreds of vulnerability research submissions each month as part of our normal contributor program," Greenwood told internetnews.com. "We expect to get many more than six submissions that may qualify for this promotion."

Microsoft does not endorse the challenge, and Greenwood said the company has not contacted VeriSign about the challenge. "We have a close working relationship with Microsoft and responsibly make them aware of vulnerabilities as we discover them," Greenwood said.

That's not to say that Microsoft isn't aware of the iDefense challenge.

A Microsoft spokesperson told internetnews.com that Microsoft is aware of iDefense offering compensation for information regarding security vulnerabilities. The spokesperson added that Microsoft does not offer compensation for information regarding security vulnerabilities and does not encourage that practice.

"Our policy is to credit security researchers who report vulnerabilities to us in a responsible manner," the spokesperson said.

Though Microsoft will not pay for vulnerabilities, it won't ignore the vulnerabilities exposed by the challenge, either.

"Microsoft doesn't want to speculate on the motives of third-party researchers but will say it is committed to working with them closely on the issues they bring to our attention," the spokesperson said. "Whoever handles vulnerabilities, Microsoft does encourage them to responsibly disclose the vulnerability to the affected software vendor in order to protect all customers/users."

VeriSign's iDefense customers, however, may well get the leg up on Vista and IE7 vulnerabilities, ahead of regular Microsoft users.

"Early notification of vulnerabilities is just one aspect of the research the iDefense team does," iDefense's Greenwood said. "Our customers will benefit from the challenge by knowing about potential threats before they are exploited and giving them information to assess the potential risk prior to a patch being put out by Microsoft."
