Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
Secunia and other organisations are warning of a vulnerability in Firefox 3.5 that can allow the execution of arbitrary code.
According to the Denmark-based company, "The vulnerability is caused due to an error when processing JavaScript code handling e.g. 'font' HTML tags and can be exploited to cause a memory corruption."
The vulnerability was originally disclosed by Simon Berry-Brown via milw0rm.com. His proof of concept appears to open the calculator on Windows systems.
According to SecurityFocus, the proof of concept works on Windows XP SP2 but simply causes a crash under SP3.
Judging by a discussion on Mozilla's Bugzilla bug-tracking system, this issue relates to a bug that had already been identified and fixed by the time Berry-Brown revealed his exploit, although the fix has yet to be incorporated into a released version of the open-source browser.
Firefox 3.5.1 was expected this month. The appearance of the proof of concept may spur an early release, even if some other known bugs remain unfixed.
According to some reports, the Noscript extension provides protection against this issue. Noscript can be used to allow the execution of JavaScript only if it originates from a trusted site.
