Yahoo Fixes Flaw Allowing an Attacker To Read Any User's Emails

Slashdot - Thu, 08/12/2016 - 4:45pm
Yahoo says it has fixed a severe security vulnerability in its email service that allowed an attacker to read a victim's email inbox. From a report on ZDNet: The cross-site scripting (XSS) attack only required a victim to view an email in Yahoo Mail. The internet giant paid out $10,000 to security researcher Jouko Pynnonen for privately disclosing the flaw through the HackerOne bug bounty, In a write-up, Pynnonen said that the flaw was similar to last year's Yahoo Mail bug, which similarly let an attacker compromise a user's account. Yahoo filters HTML messages to ensure that malicious code won't make it through into the user's browser, but the researcher found that the filters didn't catch all of the malicious data attributes.

Samsung Plans All-Screen Design in New Galaxy S8 Phones

Slashdot - Thu, 08/12/2016 - 3:25pm
Samsung may have big plans to overcome the whammy of its disastrous Galaxy Note7 this year. The company is reportedly planning to push the boundaries of design with the next flagship smartphone, dubbed the Galaxy S8. The smartphone, which was recently pegged to ship without a headphone jack, will have an "all-screen" design, Bloomberg is reporting. The report adds that there might not be a home button -- at least the way we know it -- and that any part of the lower display will serve as a fingerprint scanner. From the report: The bezel-less displays will provide more viewing real estate while a virtual home button will be buried in the glass in the lower section. Samsung needs the Galaxy S8 to be a hit after suffering through the Note 7 debacle that tarnished its brand, led to an embarrassing recall and may cost the company more than $6 billion. While Samsung is targeting a March release of the S8, that could be delayed until April, the people said. Samsung is adopting tougher testing procedures in the wake of the Note 7 debacle that could push back the launch by about a month, one of the people said.

Microsoft Officially Closes Its $26.2B Acquisition of LinkedIn

Slashdot - Thu, 08/12/2016 - 2:48pm
After getting its final European Commission approvals earlier this week, Microsoft and LinkedIn today announced that Microsoft's $26.2 billion acquisition of LinkedIn, the social networking site, has officially closed. From a report on TechCrunch: The news comes six months after news first broke of the deal. In an internal memo, LinkedIn CEO Jeff Weiner went through the areas where the two companies would be working together, and how they will in other ways remain independent. LinkedIn today has over 400 million registered users, making it the largest social networking site focused on the working world. People use the service both to make work connections with other people in their fields, but also to look for jobs and hire people. As we reported earlier this week, the fact that LinkedIn essentially has a dominant position in this area meant that Microsoft had to make concessions to the EC about how it would work to allow other social networking sites to integrate on its platforms.

Microsoft Wants To Enable Cellular PCs, But Will Carriers Bite?

Slashdot - Thu, 08/12/2016 - 2:05pm
Microsoft is aiming to enable the installation of non-removable programmable SIM cards and data radios in PCs and Windows tablets. In the company's vision, users will then be able to purchase cellular data for those cards through the Windows Store. The announcement was made at the company's WinHEC conference for device manufacturers in Shenzhen, China. From a report on ComputerWorld: Users would also get settings to help them better manage the use of data plans, so it's easier for them to control how much data apps can suck up. But there's a wrinkle in that plan: Cellular carriers will have to get on board with selling plans through the Windows Store, which will likely be a tougher sell.
