Apple has released a new version of its QuickTime software, partly to repair eight serious security vulnerabilities. Apple confirmed that the vulnerabilities make both Macs and Windows PCs susceptible to malicious files which, when opened with QuickTime, could give the attacker full control over a computer running the software. The problems lie in the way QuickTime handles a number of formats: QuickTime, MIDI, 3GP, PICT and QTIF files, according to the Apple alert. Security researchers have increasingly been targeting applications in recent months, claiming that hackers are more focused on widely used programs than operating systems that are becoming more secure.
