Buffer overflow vulnerability in PDFium PDF reader affects Google Chrome


The name PDFium might not be immediately familiar, but if you're a Chrome user there's a high chance you're using it to view PDFs. The PDF viewer is built into Google's browser, and a vulnerability has been discovered in the jpeg2000 library which could allow for malicious code to be executed.

Unearthed by Aleksandar Nikolic from Cisco Talos, the heap buffer overflow vulnerability could be exploited by simply getting a user to open a PDF document with an embedded jpeg2000 image. The National Vulnerability Database entry warns that the security flaw affects versions of "Chrome before 51.0.2704.63 [and] allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PDF document".

Majority of web services and mobile APIs are unsecure

Google finds security questions are crap because your answers are fake

More than 60 percent of web services, or mobile app APIs have at least one high-risk vulnerability, which can potentially lead to a compromised database. Those are the results of a new and comprehensive report by High-Tech Bridge, summing up the trends in web security for the past six months.

The report also says that in case a website is vulnerable to cross-site scripting (XSS), it is also vulnerable to other critical flaws, in at least 35 percent of cases. Other vulnerabilities include SQL injection, XXE or improper access control.

More than half of enterprises believe cloud apps are as secure as on-premise

Cloud Security Lock

However, a new study by data protection company Bitglass suggests that this view is changing as cloud apps mature. 52 percent of organizations are now confident that cloud apps are as secure as premises-based apps, up from 40 percent a year ago.

Connected cars take data security concerns in new directions

Connected car dash

Modern-day computers began trickling into the auto industry with cars like the 1971 Chrysler Imperial, which was one of the first to offer anti-lock brakes controlled by an electronic sensor system. Some 45 years later, the growth in computer-based car technology shows no signs of stopping. A number of Chevy vehicles, for instance, will provide you with a standard mobile Wi-Fi hotspot and 4G LTE connectivity for less than $20,000. And for folks who can afford a Tesla, that brand's "Autopilot" nearly lives up to its name. But as we've seen in other fields, as the potential benefits of connectivity increase, so does the potential for cybercrime.

Consider something as basic as mobile Wi-Fi. While Chevy is the only mainstream brand to supply that technology with 4G connectivity right now, a growing number of premium brands offer it, and a growing number of customers want it. Yet while mobile Wi-Fi gives you the same kind of online access as you'd get at your home or office, it also opens you up to all the same security issues you face there, from worries about passwords and personal data being captured, to concerns over the automakers' own security protocols.

Snooper's Charter, aka the Investigatory Powers Bill, voted into UK law


The controversial Snooper's Charter -- or the Investigatory Powers Bill as it is officially known -- has been voted into law by UK MPs. An overwhelming majority of politicians (444 to 69) voted in favor of the bill which has been roundly criticized by both the public and technology companies.

The Investigatory Powers Bill grants the UK government, security, and intelligence agencies greater powers for monitoring internet usage, as well as permitting bulk data collection and remote hacking of smartphones. The law allows for the kind of mass surveillance that Edward Snowden warned about, and while the bill may have passed a majority vote, there are still those who fear not enough has been done to safeguard individuals' privacy.

Enterprises struggle to evaluate security risks

Risk puzzle piece

Many organizations rely on the Common Vulnerability Scoring System (CVSS) to evaluate cyber risks, but a new report suggests that relying on the score alone is not enough.

NopSec, a provider of cybersecurity precision threat prediction and remediation solutions, has released its 2016 State of Vulnerability Risk Management report. This suggests that in addition to CVSS, subscores combined with other factors such as context, social media trend analysis, and data feeds deliver a better risk evaluation and prioritization.

TeamViewer denies being hacked, blames users, and introduces new security measures


In the last couple of weeks there have been a huge number of reports from TeamViewer users that their computers have been hijacked. In addition to this, users of the remote access tool have complained of funds being extracted from PayPal and bank accounts. But TeamViewer insists that there has not been a security breach, instead shifting the blame to users.

The company says they are in the habit of reusing the same passwords for a number of apps and services. It suggests that recent high profile security breaches -- such as the password dumps from MySpace and LinkedIn -- have allowed cyber criminals to learn TeamViewer log in credentials. Despite laying the blame firmly at the feet of users, the company is introducing two new measures to help increase security.
