Apple has released updates to its QuickTime media player to fix eight security vulnerabilities.

The California-based company rated the flaws as serious, since they affect both Macs and Windows computers. The vulnerability could be exploited by a hacker to create a malicious file, which could cause the machine to be compromised, Apple said in a security announcement.

Users of QuickTime 7 are advised to upgrade to QuickTime 7.1.5, which delivers numerous bug fixes and addresses critical security issues, Apple said in an alert.

In January, a bug was detected in the media player software by researchers as part of the Month of Apple Bugs project. The vulnerability affected the way the feature ran Real Time Streaming Protocol (RTSP), which could be used by a malicious user to compromise the user’s computer.

All updates are available to download from the Apple website.
