Firefox Zero-Day DoS Discovered

Filed under
Moz/FF

A Javascript handling issue in the latest version of the Firefox browser can be exploited to cause a buffer overflow and crash the browser.

Proof of concept code provided in the Milw0rm exploit advisory did cause a Firefox 1.5.0.2 browser to crash immediately. That behavior prompted both the Mozilla feedback agent and Microsoft's error reporting tool to launch and request permission to send the details of the crash along to the respective organizations.

The exploit exists in Linux as well as Windows versions of Firefox.

KDE Says Its Next Plasma Desktop Release Will Start a Full Second Faster

According to the developer, the upcoming KDE Plasma 5.13 desktop environment release will start a full second faster than previous versions because of the removal of the QmlObjectIncubationController component, which apparently slowed down the entire desktop, and promises to let users pin apps on the panel that contain spaces in their desktop file names. Goodies are also coming to the upcoming KDE Applications 18.04 software suite this spring, which makes creating of new files with the Dolphin file manager instantaneous, improves drag-and-drop support from Spectacle to Chromium, and lets users configure the Gwenview image viewer to no longer display the image action buttons on thumbnails when they hover with the mouse cursor over them.

Why open source could be IBM's key to future success in the cloud

Do those same developers need IBM? Developers certainly benefit from IBM's investments in open source, but it's not as clear that those same developers have much to gain from IBM's cloud. Google, for example, has done a stellar job open sourcing code like TensorFlow and Kubernetes that feeds naturally into running related workloads on Google Cloud Platform. Aside from touting its Java bonafides, however, IBM has yet to demonstrate that developers get significant benefits for modern workloads on its cloud. That's IBM's big challenge: Translating its open source expertise into real, differentiated value for developers on its cloud. Read more
