New version of Apple's QuickTime multimedia player repairs five vulnerabilities, all of which could result in a hacker taking control over a person's PC Apple has again released a new version of QuickTime, its multimedia player that has been plagued by software vulnerabilities.The latest version, 7.5, repairs five vulnerabilities, all of which could result in a hacker taking control over a person’s PC. Four out of the five problems affect both Apple’s OS X and Microsoft’s XP and Vista operating systems.Apple posted details of the flaws on its Web site. Two of the problems concern PICT image files, which could be engineered in order to exploit the software vulnerabilities, causing the machine to crash or execute other code.Apple wrote that the other three vulnerabilities could also be exploited by maliciously crafted files. Content in the AAC audio, Indeo video, or QuickTime formats could be built to take advantage of those problems.In April, Apple released 11 patches for QuickTime, some of which could have also allowed a hacker to execute malicious code on a machine. Four patches were issued in January to fix critical flaws as part of version 7.4. Software DevelopmentSecurity
