It was a busy week this week for both Apple and Microsoft, after the two tech giants were forced to patch critical flaws in their products, while Google’s spat with China continued and social networks were found wanting once again.
First, Microsoft’s Internet Explorer product was was at the centre of another security scare, with the firm forced to issue an out-of-cycle patch for IE6 and IE7 – the second time this year Redmond has had to release a patch outside its regular schedule.
"The out-of-band security bulletin is a cumulative security update for IE and will also contain fixes for privately reported vulnerabilities rated 'critical' on all versions of IE that are not related to this attack," said the company.
On the same day, Apple issued major security updates for Mac OS 10.5 (Leopard) and Mac OS 10.6 (Snow Leopard), as well as additional performance and stability updates for Snow Leopard. The security update includes 69 fixes for various components in Leopard and Snow Leopard, including nine vulnerabilities in QuickTime and four in the ImageIO component.
There was more trouble for Google this week as the tit for tat battle between the web giant and the Chinese government continued.
It emerged early in the week that some of Google’s mobile services were being blocked by China, while a senior Google security researcher argued that the attacks it suffered in January originating in the region represented a much wider threat to the internet.
